Glaucoma is the name for several eye diseases that damage the optic nerve, a core part of your visual system. This damage is slow, painless, and can lead to vision loss if not managed.

Your optometrist is an important member of your healthcare team. They play a key role in protecting your eye health and vision and they can also diagnose and treat glaucoma.

Here at River Heights Eyecare, our team is equipped to recognize glaucoma early and offer a range of methods for managing the disease.

What Role Do Optometrists Play Against Glaucoma?

Optometrists are primary healthcare professionals who specialize in eye care and vision health. Their training involves completing a 4-year Doctor of Optometry degree, which includes education in diagnosing, managing, and treating eye diseases and disorders. Optometrists are licensed to perform eye exams, prescribe corrective lenses, and detect various eye abnormalities.

Optometrists are primary eye care providers and serve as the first line of defence against glaucoma. They conduct comprehensive eye exams, which include screening for signs of increased eye pressure (a significant risk factor) and other signs associated with glaucoma. In Alberta, they can prescribe therapeutic medications to manage the disease.

Types of Glaucoma

There are several types of glaucoma, each with its own causes and risk factors: 

• Open-angle glaucoma is the most common type. It occurs when the drainage angle of the eye becomes less efficient, leading to an increase in IOP. It develops slowly without noticeable symptoms, making routine eye exams essential for detecting it. 
• Angle-closure glaucoma occurs when the eye’s drainage angle becomes completely blocked, causing a sudden increase in IOP. It can develop slowly (chronic) or suddenly (acute).
• Normal-tension glaucoma damages the optic nerve even though IOP is within the normal range. Other factors, such as blood flow and genetics, may play a role in this glaucoma, making routine eye exams essential for detecting it.  
• Secondary glaucoma can also develop as a result of other eye conditions or diseases, such as trauma, inflammation, or cataracts. 

How Is Glaucoma Diagnosed?

A comprehensive eye exam is essential for diagnosing any type of glaucoma. It typically includes:

• Tonometry: This test measures the internal pressure of the eye. Elevated pressure is a significant risk factor for glaucoma.
• Ophthalmoscopy: This test examines the inside of the eye, including the optic nerve, retina, and blood vessels, for signs of damage.

Additional tests include: 

• Gonioscopy: This test examines the angle in the eye where the iris meets the cornea to determine whether it is open or closed, which is important in diagnosing angle-closure glaucoma.
• Optical coherence tomography (OCT): This is a sophisticated scanning system that creates a detailed image of the optic nerve and surrounding tissues.
• Perimetry: Also known as a visual field test, perimetry measures all areas of eyesight for blind spots. Peripheral vision is often affected by glaucoma first.

If these tests indicate the possibility of glaucoma, your optometrist may either manage your care themselves or refer you to an ophthalmologist. 

Ophthalmologists are medical doctors who specialize in the eye and can provide a higher level of intervention, including surgical treatments.

The Importance of Early Detection

Early detection and treatment are crucial for managing glaucoma. Optic nerve damage and vision loss caused by glaucoma can be reversed, but with proper intervention, we can slow or even stop its progression.

These routine visits are especially important for individuals at higher risk for the disease:

• Those with a family history of glaucoma 
• Anyone over 40 and especially over 60
• Have nearsightedness (myopia)
• High internal eye pressure

By starting treatment in the early stages of glaucoma, optometrists can manage the disease more effectively, maintaining the patient's quality of life and visual function. Treatment initiated after significant damage has occurred can only mitigate further loss but cannot reverse past damage. Early treatment is not just about preserving vision but also about minimizing the impact on overall well-being.

Protect Your Vision with Regular Eye Care

At River Heights Eyecare, our optometrists are highly trained in glaucoma detection and management. We can effectively manage glaucoma through medication and ongoing monitoring for many patients. In cases requiring specialized care, we can refer you to an ophthalmologist.Routine eye exams are a key component of preventive health care and can help protect you from vision loss caused by glaucoma.

Multifocal lenses contain multiple prescriptions in one lens, allowing you to enjoy clear vision at various distances without needing multiple pairs with varying prescriptions. Whether you're reading a book, driving, or using a computer, these lenses are ideal for people with more than one visual concern.

Adapting to multifocal lenses requires time to adjust, continuous wear in the beginning, and professional guidance. Your eye doctor can perform a contact lens exam to determine the right contacts for your vision needs.

What Are Multifocal Lenses?

Like multifocal lenses in eyeglasses, multifocal contact lenses are designed to provide clear vision at multiple distances. Unlike single-vision lenses that correct only one distance, multifocal contact lenses have 2 or more prescriptions to address near, intermediate, and far vision.

Types of Multifocal Contact Lenses

Multifocal lenses come in 2 types that work differently. Each type has its benefits and the type that suits you will depend on your specific visual needs and lifestyle. Your eye doctor can help you find the right match.

1. Simultaneous Multifocal Contact Lenses

These have specific regions on the lens for near and far viewing. Simultaneous multifocal lenses are classified into two different designs: concentric and aspheric. The concentric design has distance power in the middle of the lens, surrounded by rings of near and distance powers. The aspheric design also has distance power at the center, but presents a gradual transition to intermediate and near powers as you move outward from the middle.

2. Segmented Multifocal Contact Lenses

Similar to bifocal glasses, the segmented multifocal contact lens has distinct sections for different distances with an obvious line of separation. Distance power is at the top and middle zones of the lens, and near power is at the bottom zone.

Who Can Benefit from Multifocal Lenses?

If you have multiple refractive errors, like nearsightedness and farsightedness, multifocal contact lenses can help correct them and provide vision clarity at varying distances. Multifocal lenses can also be prescribed for people with presbyopia and astigmatism.

Presbyopia

Presbyopia is a natural part of aging where the eye's lens loses its flexibility, making it difficult to focus on close objects. Multifocal lenses are an excellent solution for this condition, offering a convenient alternative to bifocal or reading glasses.

Astigmatism

Astigmatism is when the eye has an irregularly shaped cornea (clear front surface of the eye) or lens that prevents light from focusing on the retina (the light-sensitive tissue at the back of the eye), causing blurry or distorted vision at all distances.

Since multifocal contact lenses help you see near, intermediate, and far distances, they can be helpful for people with more than one refractive error.

Tips for Adapting to Multifocal Lenses

Fitting specialty multifocal contact lenses does take more time and expertise than fitting regular contact lenses. For these reasons, here are some tips for adapting to them.

Give It Time

Like adapting to new prescription for glasses, adapting to multifocal lenses can also take some time. Your brain needs to adjust to comfortably processing multiple visual zones. Initial discomfort, dizziness, or blurry vision is normal in the beginning.

Be Patient & Consistent

It might take a few tries to find the right fit and prescription. Don't be discouraged if the first pair isn't perfect. Work closely with your eye doctor to fine-tune your lenses until you achieve optimal vision.

Follow Professional Guidance

Your eye doctor will provide you with specific instructions on how to wear and care for your lenses. Follow these guidelines for a smooth transition and to avoid any complications. If discomfort persists, make sure to speak to your eye doctor.

Multifocal Lenses vs Reading Glasses

Reading glasses are effective but can be inconvenient. You constantly have to put them on and take them off. Multifocal contact lenses eliminate this hassle by providing clear vision at all distances, allowing you to go about your day without interruption.

Monovision Contacts

Multifocal lenses provide a natural visual experience, closely mimicking how your eyes naturally function, but if these designs don’t work for you, your doctor might suggest monovision contacts.

Unlike bifocal and multifocal lenses, monovision contacts use two single-vision lenses, one prescribed for near vision and the other for far vision. 

Addressing Common Concerns About Multifocal Lenses

Modern multifocal contact lenses are made from advanced materials that enhance comfort. You can get multifocal contact lenses in soft and rigid gas-permeable materials. While there may be an adjustment period, daily and extended-wear options can provide comfort.

Initial blurriness is common but usually temporary. Your eyes and brain need time to adapt to the new visual zones. Consistent wear and follow-up visits with your eye doctor can help fine-tune your prescription for optimal clarity. 

Because of their complexity, multifocal lenses can cost more than single-vision lenses. But the convenience they provide often outweighs the cost.

Near & Distance Vision Correction

Multifocal contact lenses offer a convenient and seamless way to enjoy clear vision at all distances, enhancing your daily life. If you're tired of juggling different glasses or want to explore a more convenient vision correction option, multifocal contact lenses might be right for you.Book an appointment with River Heights Eye Care today to discuss your options and start your journey towards clearer, more comfortable vision.

Contact lenses are a popular choice for vision correction, offering convenience and comfort for millions of people. However, like any medical device, it's essential that users understand their lifespan and how they can be affected over time. 

Unlike food, where an expiration date relates to quality, the expiration date on contact lens packaging is not just a suggestion—it's an essential indicator of the lens's viability and safety. Therefore, it is crucial to follow the expiration date accurately. 

River Heights Eye Care is here to help you determine the right contacts for your needs–we encourage you to start with an eye exam.

Understanding Expiry Dates

Contact lenses typically have an expiry date printed on the packaging. The manufacturer determines this date based on various factors, including the materials used, manufacturing processes, and sterilization methods. It's essential to adhere to this expiry date and only use lenses up to that date. 

The expiry date is a guideline for the lens's effectiveness and safety. Over time, contact lenses can degrade, leading to changes in their physical properties, such as flexibility and oxygen permeability. Using expired lenses can increase the risk of eye infections, discomfort, and reduced vision clarity.

Factors Affecting Shelf Life

Several factors can affect the shelf life of contact lenses, even before their expiry date:

• Storage Conditions: Proper storage is critical for maintaining the quality of contact lenses. Lenses should be stored in their original packaging and kept clean, dry, and in well-ventilated areas, away from direct sunlight and moisture.
• Handling Practices: Mishandling of contact lenses, such as touching them with dirty hands or using saliva to moisten them, can introduce harmful bacteria and contaminants, shortening their shelf life and increasing the risk of eye infections.
• Frequency of Use: The frequency of lens wear can also impact shelf life. Daily disposable lenses are designed for single use and should not be worn overnight. Extended-wear lenses may have a longer lifespan but require proper care and maintenance.
• Cleaning and Disinfection: Following the recommended cleaning and disinfection routine for reusable lenses is essential for prolonging their shelf life and ensuring eye health. Failure to clean and disinfect lenses properly can lead to microbial buildup and lens deterioration.

Safety Considerations

Using expired or degraded contact lenses can pose significant risks to one's eye health, often leading to conditions that require medical attention, including: 

Eye Infections

When contact lenses expire, the sterility of the lens and the solution it’s stored in can be compromised. This breakdown creates an environment conducive to microbial growth. Bacteria, fungi, or protozoa can contaminate the lens, leading to severe eye infections.

Specific Infections

• Keratitis: Refers to an infection of the cornea. Symptoms can include redness, pain, excess tearing, and blurred vision. Severe cases of keratitis can lead to corneal scarring, which might necessitate a corneal transplant.
• Conjunctivitis (Pink Eye): Refers to inflammation of the conjunctiva—the thin, clear tissue over the white part of the eye. It can result in itchiness, redness, discharge, and a gritty feeling in the eye. Bacterial conjunctivitis can be caused by the use of contaminated lenses.

Corneal Abrasions

• Deterioration Impact: Over time, the smooth surface of contact lenses can become compromised due to material degradation, leading to the development of tiny cracks or tears on the surface of the lens, making it rough or abrasive.
• Consequences: When these roughened lenses are worn, they can scratch the cornea (corneal abrasion), leading to significant discomfort, sensitivity to light, redness, and a sensation of having something stuck in your eye. Corneal abrasions increase the risk of developing a secondary bacterial infection, adding further complications.

Reduced Vision Quality

• Material and Surface Changes: The quality of contact lenses can deteriorate over time due to changes in the lens material or the accumulation of microscopic deposits that cannot be removed through cleaning. These alterations can directly impact how light is focused by the lens, leading to compromised vision clarity.
• Symptoms and Impact: Individuals using expired or degraded lenses might experience blurred vision, increased sensitivity to light, burning or stinging, or even double vision. These visual disturbances not only reduce the quality of life but can also pose safety risks, especially while driving or operating machinery.

Preventive Measures

To avoid these serious risks, it’s essential to adhere to the expiration dates provided by contact lens manufacturers and replace lenses as recommended by an eye care professional. Proper lens care, including regular cleaning and storage in fresh solution, is also vital in maintaining the integrity and safety of contact lenses.

Regular eye exams are crucial for contact lens users. These exams enable early detection and treatment of any potential eye health issues and provide an opportunity for eye care professionals to review and reinforce proper lens care practices.

Safeguarding Your Vision & Eye Health

Contact lenses do have a shelf life, and it's essential to adhere to the expiry date provided by the manufacturer. Factors such as storage conditions, handling practices, and cleaning routines play a significant role in determining the lifespan and safety of contact lenses. 

By following proper care and maintenance guidelines, individuals can ensure the longevity of their lenses and protect their eye health. 

Regular eye exams and consultation with an eye care professional are also crucial for monitoring eye health and ensuring the appropriate use of contact lenses. Remember, when in doubt, always err on the side of caution and replace your lenses as recommended. 

Your eyes deserve nothing less than the best care possible, that’s why we encourage you to book an appointment with us at River Heights Eye Care.

Many people deal with dry eyes daily. But as uncomfortable as dry eyes are, they can become much more frustrating when accompanied by a headache. When your eyes are burning and your head is pounding, you might wonder if your dry eyes caused a headache.

Dry eyes and headaches share some similar causes, like underlying medical conditions or environmental factors. While one condition doesn't typically cause the other, they can often make symptoms worse for each other. 

What Is Dry Eye Disease?

Dry eye disease is a lot more common than most people think. It's believed that at least 30% of Canadians experience dry eyes at some point in their lives. But what is dry eye disease exactly?

Your eyes are covered by an extremely thin film of tears. These tears are spread evenly over the eye's surface every time you blink and are responsible for flushing away contaminating particles while hydrating the eye. They do all of this while providing a smooth and clear surface that allows light to pass through unobstructed.

This tear film is made of three layers:

• The mucus layer keeps the tears attached to the surface of the eye.
• The watery aqueous layer helps protect and nourish the eye.
• The oily outer layer prevents the tear from evaporating.

When your tear film is stable, it keeps the eye protected. However, what if it's unstable? An imbalance in the tear film, whether due to the quantity or quality of the tears, can lead to the tear evaporating too quickly. This leaves the eye unprotected, inflamed, and irritated. When this situation arises, it's called dry eye disease.

The Symptoms of Dry Eye Disease

When your tear film isn't balanced properly, you'll likely notice almost immediate inflammation. This often feels like something is burning in your eye, or someone has thrown a few grains of sand under your eyelid. This is one of the most obvious symptoms of dry eye disease, but other signs can include:

• Visible redness or a watery discharge
• Blurry vision
• Light sensitivity
• Overly watery eyes, where the eye floods itself with poor-quality tears

Overall, these symptoms can cause significant discomfort. It may be harder to focus on work, and enjoying your hobbies may cause you more irritation than pleasure. This becomes much more problematic when headaches are involved.

The Link Between Dry Eyes & Headaches

It's not unusual to experience dry eyes and headaches simultaneously. However, the extent of this relationship isn't fully understood. While people who experience chronic migraines are much more likely to develop dry eyes, this could be due to several potential reasons.

When your tear film is unstable, it doesn't provide as smooth a surface as when it's healthy. When light passes through, it can scatter, potentially affecting how it refracts as it enters the eye. This can make it more difficult for the brain to process what it's seeing, putting additional strain on your visual system and possibly leading to headaches.

On the other hand, dry eyes increase inflammation in the area around your eyes. This can put additional strain on surrounding areas—like the brain—which can also lead to a headache.

Regardless of the exact cause, there does remain a link between the two. Both dry eye disease and headaches have similar symptoms, like inflammation and light sensitivity. When one flares up, it could trigger the other, leading to the correlation.

However, a study performed in 2015 found that some patients who experienced both chronic migraines and chronic dry eye disease had a structural difference in their eyes. The nerves in the corneas of those who did not suffer from chronic migraines differed from those who did. 

While this link isn't fully understood, the results were simple—people with migraines are significantly more likely to develop dry eyes.

Can Your Optometrist Treat Dry Eye Disease?

There is good news, though. In most situations, your optometrist can treat your dry eyes and bring you lasting relief. Our team at River Heights Eye Care is here to help—but finding relief could be as simple as making some adjustments at home.

When looking for relief from dry eye disease, it helps to:

• Use prescription eye drops or ointments as recommended by your optometrist.
• Use warm compresses to stimulate the areas around the eye and promote healthy tear production.
• Use eye masks while sleeping to help keep your eyes lubricated.
• Follow a balanced diet, or take supplements to encourage healthy tear production.
• Avoid tobacco products, as they can inflame the eye.

It can also help to make environmental changes to reduce additional strain on your eyes. If you constantly use a fan, aim it away from your face to prevent drying out your eyes. It can also help to use a humidifier in rooms you spend a lot of time in.

Clear vision is a treasured sense: a gateway to our world and an informer of experiences. It sounds dramatic, but we rely on our vision for so much, and it’s easy to take it for granted. However, 2 common eye conditions, cataracts and glaucoma, can cloud our vision if left undetected and untreated. While they can affect your vision similarly, they’re very different diseases.

The main difference between the pair is that cataracts are the natural clouding of the eye’s lens, while glaucoma involves damage to the optic nerve, typically due to increased eye pressure. However, one thing they have in common is your optometrist can detect both with a comprehensive eye exam.

What Are Cataracts?

Cataracts are a leading cause of vision loss in Canada. They cause the eye’s lens to become cloudy, which then causes light to scatter across the retina and results in blurry vision. The primary culprit behind cataracts is protein buildup in the lens, which happens naturally as we age.

However, other factors can cause cataracts to develop early or with greater severity, including:

• Genetics
• Eye injury
• Diabetes 
• Obesity
• UV exposure
• Smoking
• Excessive alcohol consumption
• High blood pressure
• Glaucoma or retinal eye surgery
• Medications, such as steroids

Think of cataracts as a slow progression, gradually dimming your perception like an aging photograph.

Cataract Symptoms

The symptoms of cataracts may vary considerably, but common signs include:

• Blurred vision
• Sensitivity to light
• Seeing halos around lights
• Colours appearing faded

Cataract symptoms can progress, affecting night vision and leading to significant vision complications if left untreated.

Treatments for Cataracts

The good news about cataracts is they're treatable. Diagnosis typically begins with a comprehensive eye exam that may include dilating your pupils to allow your eye doctor to examine the lens for any signs of cataracts.

Optometrists can address early symptoms with prescription eyeglasses. Once cataracts start severely affecting your vision, you may require surgery to remove the cloudy lens and replace it with an artificial one.

What Is Glaucoma?

Glaucoma, on the other hand, isn’t a single condition but a group of eye diseases that damage the optic nerve, often due to elevated pressure in the eye. Glaucoma is challenging because it can sneak up on you without warning, silently eradicating your peripheral vision. Symptoms might not manifest until the disease has progressed and damage is done. 

There are several types of glaucoma, but the most common varieties include:

• Open-angle glaucoma: In open-angle glaucoma, the eye structures appear normal, but the fluid does not flow out properly, causing a pressure buildup. This makes up about 90% of all glaucoma cases.
• Angle-closure glaucoma: Angle-closure glaucoma occurs when the iris is very close to the drainage angle in the eye and can block fluids from draining.
• Secondary glaucoma: Secondary glaucoma results from injury, surgery, infection, or other eye abnormality.
• Normal-tension glaucoma: While glaucoma is usually caused by increased pressure inside the eye, normal-tension glaucoma occurs when eye pressure is still in the “normal” range.

Risk Factors for Glaucoma

Since glaucoma can be so stealthy, knowing the risk factors helps determine if you need to be on the lookout. Risk factors for glaucoma include:

• Age
• Family history
• Cardiovascular conditions
• Eye-related health conditions
• Injury or eye surgery

There's no turning back the clock on vision loss—so early detection is paramount. Regular check-ups with an optometrist can make all the difference.

Glaucoma Diagnosis & Management

Like cataracts, diagnosis involves a full eye exam focusing on the optic nerve. Tonometry is a common test, using a puff of air or a gentle probe to test your eye pressure. If diagnosed, your doctor can try to manage glaucoma's progression through medication, laser treatment, or, if necessary, traditional surgery.

The key for most treatments is keeping eye pressure stable to avoid optic nerve damage.

The Differences Between Cataracts & Glaucoma

Cataracts and glaucoma are both conditions that can slowly rob you of your sight, but they have different mechanics and, therefore, treatments.

Cataracts are a natural part of aging, like hair turning grey. Environment and genetic factors can affect when they first appear, but treatment with cataract surgery is very common.

Glaucoma is typically associated with increased eye pressure and usually means there’s something wrong with your eye. Once the damage is done, it can’t be reversed. This means that much of the focus for glaucoma is on preventing vision loss or preserving what vision remains.

Proactive Prevention & Early Detection in Cochrane

Though both serious, cataracts and glaucoma are markedly different in their nature and impact on our vision. Understanding where these conditions diverge is the first step in taking control of your eye health.

Routine eye check-ups can often be the difference between suffering from a vision-related issue and proactively addressing it before it’s too late. Our River Heights Eye Care team can detect issues early on with annual comprehensive eye exams, allowing you to adopt strategies to potentially slow them down. If you're experiencing any changes in your vision or are at a higher risk for these conditions due to your age or medical history, book your eye exam today. Your eyes are with you for the long haul, so look out for them as they guide you through life's wonders!

When it comes to occupational hazards for office workers, students, and gamers, eye strain sits high on the list of common issues. Many of us experience symptoms of eye strain, often wondering how long it will last and seeking solutions for relief. 

First, we'll look at what eye strain is before diving into its causes and symptoms and offer practical advice on reducing discomfort and promoting eye health. We'll also cover eye strain relieving tips at home and will let you know when to seek professional eye care. 

Ultimately, the duration of eye strain depends on several factors, including the severity of the strain and how quickly mitigating actions are taken. By employing eye health tips, taking regular breaks, and seeking professional advice, one can alleviate the discomfort of eye strain and protect one's vision.

What is Eye Strain?

Eye strain, also known as digital eye strain or computer vision syndrome, is a group of eye and vision-related problems resulting from prolonged use of digital devices. From computers to smartphones, our eyes are constantly adjusting to the screens' brightness, contrast, and flicker. 

According to the Canadian Ophthalmological Society, eye strain occurs when the muscles in your eyes get tired from intense use, which can happen from driving long distances or staring at screens for long periods.

In fact, eye strain might be a possible cause behind the growing trend of myopia in both adults and children around the world, and preventative measures work best in dealing with eye strain. 

Causes of Eye Strain

Digital eye strain has been a growing concern in Canada, particularly with the increased screen time associated with modern lifestyles. Key factors include:

1. Staring at digital devices without breaks: Even reading a screen for a short time can contribute to eye strain.

2. Poor lighting: Working in dimly lit or overly bright environments can lead to eye strain.

3. Improper screen distance and angle: Holding digital devices too close or at an awkward angle puts a strain on the eyes, leading to discomfort and fatigue.

4. Screen glare: reducing the glare on your eyes and screen can make a big difference in reducing eye strain. 

4. Uncorrected vision problems: People who have uncorrected vision problems such as nearsightedness, farsightedness, or astigmatism may experience more severe eye strain when using digital devices.

A study on the Management of Digital Eye Strain highlights that even minor uncorrected vision problems can significantly increase the chance of experiencing eye strain.

Symptoms of Eye Strain

Typical symptoms of eye strain can include:

• Sore eyes
• Tired eyes
• Burning eyes 
• Watery eyes
• Dry eyes
• Blurred vision
• Double vision
• Headache
• Sore neck
• Sore shoulders 
• Sore back
• Increased sensitivity to light

These symptoms may not necessarily be solely caused by digital eye strain and, if persistent, should be evaluated by a healthcare professional.

Reducing Eye Strain at Home

Eye strain relief at home focuses on a few simple changes to your environment and habits. The Canadian Association of Optometrists suggests practicing the 20-20-20 rule: every 20 minutes, take a 20-second break and focus your eyes on something at least 20 feet away. Other tips for reducing eye strain include: 

• Adjusting your screen settings
• Ensuring proper lighting
• Setting up an ergonomic workspace
• Blink more while working with a screen
• Use artificial tears
• Use computer glasses
• Reduce glare

Professional Help for Eye Strain

If you’re experiencing persistent symptoms of eye strain, it’s vital to seek professional help. Eye care professionals can conduct a comprehensive eye exam to rule out other causes of your symptoms and recommend appropriate treatments or corrective lenses. 

The Canadian Association of Optometrists emphasizes that regular eye exams are vital for maintaining eye health and preventing eye strain.

Eye strain can persist as long as the triggering event, and several hours after. Set yourself up for success when you know you’re going to have a digital-heavy day, or long hours on the road. If you start to feel that discomfort and fatigue, try to change tasks if you can.

Digital Eye Strain in Canada: A Closer Look 

According to the Canadian Association of Optometrists, approximately three-quarters of Canadians experience symptoms of digital eye strain, with a majority reporting that their symptoms are at least somewhat bothersome. In addition, Canadian adults spend at least 6 hours per day on digital devices.

These statistics highlight the prevalence and impact of digital eye strain in Canada and the need for preventative measures and proper treatment. With more and more people relying on digital devices for work, school, and leisure activities, it's essential to prioritize our eye health in today's technology-driven world.

Pink eye and styes are two common eye conditions that can cause discomfort and irritation. Both have similar symptoms, making it difficult to differentiate between the two. Knowing the differences between pink eye and a stye can help you receive the appropriate treatment faster.

Pink eye, also called conjunctivitis, is the inflammation or infection of the outer membrane of the eyeball and inner eyelid. Symptoms include redness, itching, and a gritty feeling in the eye. On the other hand, a stye is a painful, red bump that forms on the edge of the eyelid, often due to a bacterial infection in an oil gland.

To discern between pink eye and a style, the key is to observe the specific symptoms. While both conditions can cause redness, discomfort, and swelling, a stye is usually characterized by a distinct lump on the eyelid. On the contrary, pink eye typically affects the entire eye, accompanied by a general redness and inflammation, and possibly a discharge.

Types & Symptoms of Pink Eye

Pink eye can manifest in different forms, each with its own set of symptoms:

1. Viral Conjunctivitis: This type is usually associated with colds or respiratory infections. Symptoms may include redness, watery eyes, itchiness, and sensitivity to light. It can be highly contagious and often affects both eyes.
2. Bacterial Conjunctivitis: Caused by bacteria, this type may result in redness, discharge (yellow or green), crusty eyelids, and swollen eyelids. It can affect one or both eyes and is also contagious.
3. Allergic Conjunctivitis: Allergic conjunctivitis, triggered by allergens like pollen, dust mites, or pet dander, causes itching, redness, watery discharge, and swollen eyelids. It affects both eyes simultaneously and can be seasonal or perennial depending on the allergen.

How to Identify Pink Eye Through Its Symptoms

Identifying pink eye is relatively straightforward as it presents with distinct symptoms. Look out for:

• Redness in the whites of the eyes
• Irritation or itchiness
• Excessive tearing or watery eyes
• Discharge from the eyes, which can be clear, white, yellow, or green
• Crusty eyelids upon awakening
• Swollen, puffy eyelids
• Sensitivity to light

While some cases of pink eye may resolve on their own, others may require medication or additional care.

Prevention of Pink Eye

Pink eye can be highly contagious, so taking preventive measures is crucial. Here are some tips to prevent the spread of pink eye:

• Wash your hands regularly, especially after touching your eyes or face.
• Avoid sharing personal items such as towels and cosmetics with others.
• Practice good hygiene by disinfecting surfaces that come into contact with the infected person's eye discharge.

• Avoid touching your eyes with unwashed hands.
• If you wear contact lenses, make sure to properly clean and store them to avoid infection.
• If you have allergies, try to avoid allergens that trigger your symptoms.
• Stay home from work or school until the pink eye has cleared up to prevent spreading it to others.

Types & Symptoms of Stye

There are two types of styes:

1. External Stye: This type appears as a red, painful bump on the edge of the eyelid. It is caused by an infection in the hair follicles of the eyelash.
2. Internal Stye: This type appears as a swollen bump inside the eyelid and is caused by an infection in the oil glands.

Both types of styes can be treated with warm compresses, over-the-counter pain relievers, and occasionally antibiotics if the infection is severe. If a stye does not improve or becomes increasingly painful, seek medical attention as it may require drainage or medication.

How to Identify Stye Through Its Symptoms

If you experience any of the following symptoms, it may be a stye:

• A red, painful bump on or inside the eyelid
• Swelling and tenderness around the eye
• Discharge from the affected area
• Sensitivity to light

Styes can also sometimes cause other symptoms like blurred vision or a feeling of something in your eye. If you experience these symptoms, seek medical attention immediately.

Prevention of Styes

To prevent styes, it is important to maintain good hygiene practices such as:

• Washing your hands frequently and avoiding touching your eyes
• Avoiding sharing personal items like towels, makeup, or contact lenses with others
• Removing all eye makeup before going to bed

If you wear contact lenses, make sure to properly clean and disinfect them before each use. It is also important to replace your contact lens case every 3 months or as recommended by your eye doctor.

Differences Between Pink Eye & a Stye

While both conditions can cause redness and swelling, there are some key differences between pink eye (conjunctivitis) and a stye such as:

• Pink eye affects the conjunctiva, the clear membrane covering the white of your eye and inside your eyelids, while a stye affects the oil glands in your eyelid
• Pink eye can be caused by a virus or bacteria, whereas a stye is typically caused by bacterial infection
• Pink eye can cause watery discharge while a stye produces a thicker, pus-like discharge

Vision is one of our most critical senses, and when it starts to deteriorate, it can significantly impact your daily life. Cataracts are one such eye condition that can blur your vision and affect your overall quality of life. 

Cataract surgery can help you regain your vision. However, as with any surgery, it comes with its share of risks and disadvantages, including infection, swelling, bleeding, visual disturbances, corneal edema, and in some rare cases, retinal detachment. 

Cataract surgery is a common and safe surgery that has helped millions of people improve their vision. However, surgery is an individual decision, and you can discuss whether it’s right for you with your eye doctor.

Risks of Cataract Surgery

Cataract surgery is a common and low-risk procedure that has transformed the lives of millions by restoring clear vision. However, like any surgical intervention, it is not without its risks.

Infection Risk

Cataract surgery involves making an incision in the eye, which poses a risk of infection. While surgeons take great care to maintain a sterile environment, there is always a slight possibility of postoperative infection.

Swelling & Discomfort

After surgery, some patients may experience temporary discomfort or swelling. These are common side effects but can be bothersome for some.

Visual Disturbances

While the goal of cataract surgery is to improve vision, some patients may experience visual disturbances after surgery, such as glare or halos around lights. These symptoms are usually temporary but can affect daily activities during the initial recovery period.

Posterior Capsule Opacification (PCO)

PCO occurs when the lens capsule becomes cloudy after cataract surgery, leading to a gradual decline in vision. Although a laser procedure called YAG capsulotomy can easily address PCO, it is an additional intervention that some people may find inconvenient.

Retinal Detachment

While rare, retinal detachment is a serious complication that can occur after cataract surgery. It is essential for patients to be aware of the symptoms, such as sudden flashes of light or floaters, and seek prompt medical attention if they occur.

Intraocular Lens Complications

During cataract surgery, your natural lens is replaced with an artificial intraocular lens (IOL). The IOL comes with its own risks, such as incorrect power calculation, dislocation, or issues with the positioning of the lens.

Bleeding

Though uncommon, bleeding within the eye can occur during or after surgery, leading to potential vision issues.

Corneal Edema

Swelling of the cornea is a possible complication of cataract surgery that can affect your vision. It typically resolves with time, but you may experience blurred vision during the healing process.

The Pros & Cons of Cataract Surgery

Pros:

• Improved vision: Cataract surgery can significantly improve your vision, allowing you to see things more clearly.
• Enhanced quality of life: By restoring your vision, cataract surgery can help you regain independence and enjoy daily activities.
• Quick and safe procedure: Thanks to technological advances, cataract surgery is relatively quick and safe.
• Minimal discomfort: Most people experience minimal discomfort during and after the surgery, making the recovery process relatively smooth.

Cons:

• Potential risks: Like any surgical procedure, cataract surgery carries some risks, such as infection, bleeding, or retina detachment. However, these risks are relatively rare.
• Cost: Although Alberta Health covers certain expenses, there may be additional costs for premium lens implants, eye drops, and new glasses.
• Recovery time: While the surgery is quick, recovery may take some time. You'll need to follow postoperative instructions, take it easy for a few weeks, and see your optometrist for follow-up appointments.

Healing Process 

Healing after cataract surgery can vary from patient to patient. Some people might experience a speedy recovery, while others might face temporary blurry vision. Following postoperative care instructions, such as using prescribed eye drops and attending follow-up appointments, is crucial. 

Discomfort and itching in the eyes are common after surgery, and you may need a protective shield to prevent rubbing your eyes. Your vision should stabilize within a few weeks after surgery.

Here are some tips for recovering after cataract surgery recovery:

• Restrict physical activity and heavy lifting
• Avoid rubbing your eyes 
• Wear sunglasses in bright settings 
• Wash your eyes carefully and avoid putting soap or water into them
• Avoid cosmetics and lotions around the eyes for at least a week 
• Avoid irritants such as chemicals and dust

Have you ever wondered why your eye drops come with an expiration date? It's not a meaningless number. Expired eye drops could do more harm than good. But why do eye drops expire?

The shelf life of eye drops varies depending on their formulation. But no matter what kind you’re using, expired eye drops are no longer sterile and can cause irritation or infection.

Eye drops can be an easy and effective solution to many common eye issues, but you should consult your optometrist before putting any product in your eyes.

What Are the Different Types of Eye Drops?

Eye drops come in different formulations and types, making it essential to know which eye drops are right for you and your symptoms.

Artificial Tears

Artificial tears mimic natural tears and help lubricate the eyes, reducing dryness and irritation. They're often recommended for dry eyes caused by computer use, contact lenses, meibomian gland dysfunction, and the environment

Sometimes called lubricating eye drops, these drops come with both preservatives and preservative-free formulas. Preservatives often make these drops last longer, but the preservatives can cause irritation. Preservative-free drops are easier on sensitive eyes but don’t last as long. 

Antibiotic Eye Drops

Optometrists prescribe antibiotic eye drops to fight bacterial eye infections such as conjunctivitis (pink eye) and corneal ulcers. They must be used correctly and consistently to avoid resistance to medication. Most antibiotic eye drops only last a couple days to a month after opening. Every medication is different. 

Anti-Allergy Eye Drops

Anti-allergy eye drops are designed to prevent allergies from making your eyes itchy and watery. These drops contain antihistamines, which stop histamines from causing allergic reactions. You can buy them without a prescription, and they come in options with or without preservatives.

Why Do Eye Drops Expire?

Unlike the food in your pantry with best-before dates, expiry dates are the cut-off date when the manufacturer can guarantee the drops’ safety and effectiveness. Beyond that date, the eye drops can pose a risk to your eyes.

Lose Effectiveness

Eye drops expire mainly because they lose their effectiveness over time. The active ingredients in eye drops can break down and become less potent. This means that expired eye drops may not provide the same level of relief as fresh ones do.

Bacteria Growth

The preservatives in eye drops also break down over time, which can lead to bacteria growth, especially after opening the bottle. Using expired eye drops can increase the risk of infection or irritation to the eye.

How to Help Your Eye Drops Last

Some ways you can help maximize the lifespan of your eye drops include:

• Storing your eye drops in a cool, dry place.
• Keeping your eye drops away from direct sunlight.
• Practicing good hand hygiene when putting in eye drops.

It’s essential to clean your hands and practice good eye drop use to prevent cross-contamination from introducing harmful bacteria to the bottle.

Preservatives vs. Preservative-Free

Not all eye drops have the same expiration date. Some eye drops are preservative-free and are designed for single-use only. These drops typically have a shorter shelf life and should be discarded after one use. Multi-use eye drops can usually be used for several weeks after opening as long as they are correctly stored and have not expired.

So, how do you know if your eye drops have expired? Look for the expiration date printed on the packaging or bottle. If it has already passed, it's time to toss them out. You should also discard eye drops that appear cloudy, discoloured, or have particles floating in them. These are signs that bacteria growth may have occurred, and the eye drops are no longer safe to use.

Support Healthy Eyes with Regular Eye Exams

Eye drops can help soothe symptoms of discomfort and irritation, but a visit to your optometrist can help uncover the cause of your symptoms and identify the proper treatment for long-term relief. Schedule an eye exam with River Heights Eye Care to support your vision, maintain eye health, and preserve comfort.

Blue light lenses are gaining popularity as people become more aware of the potential damage caused by blue light to our eyes. These lenses filter out harmful blue light from digital devices like computers, tablets, and smartphones. 

While there are not enough studies to definitively prove the effectiveness of blue light lenses in reducing digital eye strain, preventing dry eyes, or protecting against macular degeneration, they can still help regulate sleep-wake cycles and circadian rhythms. This can have several benefits, including hormone regulation and increased alertness and may help manage depression and anxiety.

With these abilities, blue light lenses are excellent for those who spend a lot of time in front of screens, promoting better overall health and comfort for the eyes.

Understanding Blue Light & Its Effects on Vision

Blue light is part of the visible light spectrum and is emitted by the sun and digital devices like laptops, smartphones, and LED lights. It’s a high-energy, short wavelength. 

We need blue light from the sun as it provides many positive effects, including heightened attention, improved reaction times, and an uplifted mood. You may have heard that blue light emitted by electronics is bad for your eyes, but this claim lacks concrete scientific evidence.

However, excessive exposure to blue light, especially in the evening, can disrupt the delicate balance of your body’s innate sleep-wake cycle, affectionately known as your circadian rhythm.

Do You Need Blue Light Lenses?

Blue light lenses block blue light to minimize its impact on your circadian rhythm, which is particularly important for those who spend a lot of time using digital screens or in LED-lit rooms.

But it’s essential to be mindful of your total amount of blue light exposure, regardless of whether or not you use blue light glasses. A good rule of thumb is to limit device use in the evening and take frequent breaks during the day. 

Additionally, using dimmable lighting can replicate the soft hues of natural light and create a relaxing atmosphere that can help you fall asleep more easily.

The Benefits of Blue Light Lenses

Blue light lenses have become increasingly popular in our digital age. While there’s no proof they protect against certain eye conditions, there are well-documented benefits, particularly in regulating our sleep-wake cycle.

Hormone Regulation

Exposure to blue light, particularly during the evening, has been shown to disrupt melatonin production, the hormone responsible for regulating our sleep-wake cycle. This disruption can lead to difficulties falling asleep and achieving restful sleep. 

Blue light lenses can help mitigate the impact of blue light by limiting how much reaches your eyes, supporting the natural release of melatonin and promoting a more restful and rejuvenating sleep.

Alertness

Blue light lenses can help signal to our bodies that it’s time to wind down and prepare for a restful sleep. This, in turn, can contribute to increased alertness and productivity during the day, as we give our bodies the essential rest and rejuvenation they require for optimal performance. So, incorporating blue light lenses into our routine can be a valuable step towards achieving a well-balanced and energized lifestyle.

Depression & Anxiety Management

Research has consistently indicated a connection between disrupted sleep and susceptibility to depression and anxiety. Blue light lenses can effectively regulate our sleep-wake cycle and indirectly support mental health. These lenses promote healthier sleep patterns and overall well-being.

Blue light lenses may contribute to improved hormone regulation and alertness and provide benefits for managing depression and anxiety.

But blue light lenses are not only helpful for those who spend time in front of digital devices—they can also be beneficial for outdoor use, such as when engaging in activities in direct sunlight. These lenses help reduce glare and make it easier to focus on your activity or enjoy the scenery around you.

Always consult an eye care professional for personalized advice and recommendations regarding your eye health needs.

Additional Tips

In addition to wearing blue light glasses, there are some steps you can take to lessen the symptoms associated with too much blue light. This includes:

• Practice the 20-20-20 rule: Take a break from digital devices every 20 minutes to look at something 20 feet away for 20 seconds. This gives your eyes a break from the screen and helps them relax. 
• Use eye drops: Eye drops can keep your eyes lubricated throughout the day if you are experiencing dry eyes from blue light.
• Avoid too much screen time and sunlight: The best way to lower your exposure to blue light is by limiting how much time you spend looking at devices or in the sun. 
• Distance yourself from screens: To avoid blue light exposure, sit an arm’s length away from your screen. 
• Using screen filters: You can install or enable certain screen filters that lower blue light exposure on certain digital devices.
• Adjust your lighting: If you have LED bulbs in your home and you cannot change them, consider adding additional light sources that do not use LED bulbs.
• Wear sunglasses: If you spend a lot of time in the sun, your eyes will be exposed to large amounts of blue light. Wear sunglasses to protect your eyes. 

Taking care of your vision and eye health is a crucial component of your overall wellness. Book an appointment with your eye care professional to determine whether or not blue light glasses are the proper treatment for you.
