What Is the Long-Term Impact of Virtual Learning on Children’s Eyes?

Kids, like adults, are spending more time online. At some point during the COVID-19 pandemic, many children attended school via Zoom and completed assignments online. The trend toward more screen time — whether playing games or being in touch with friends — is likely to continue even after everyone returns to the classroom. 

We already know that prolonged screen time can cause digital eye strain as well as dry eye symptoms, among other problems in children and adults. There is some indication that extended exposure to blue light may impact the development of retinal cells. However, studies on actual subjects still need to be done to establish a clear connection. 

Dry Eyes

Spending a long time in front of screens can impact how quickly our tears evaporate, because we blink around 66% less when using a computer compared to other daily activities. When tears evaporate too quickly and aren’t replenished with blinking our eyes start to feel dry and gritty. So remember to blink every few seconds to prevent your eyes from drying out!

Blue Light Exposure

Screens, such as those that appear on computers, phones and tablets emit blue light. Recent studies have shown that overexposure to blue light can damage the retinal cells at the back of your eyes. This may increase the risk of vision issues such as age-related macular degeneration which eventually leads to permanent loss of vision. 

Excess blue light has also been shown to disrupt the circadian rhythms that regulate our sleep patterns, as it tricks your internal clock into thinking that it is the middle of the day. This may lead to difficulty in falling asleep, insomnia, and daytime fatigue.

Digital Eye Strain

Nearly 60% of people who routinely use computers or digital devices experience symptoms of digital eye strain — also called computer vision syndrome. Symptoms of eye strain include eye fatigue and discomfort, dry eye, headaches, blurred vision, neck and shoulder pain, eye twitching, and red eyes. 

Taking frequent breaks from your screen can help reduce eye strain and neck, back and shoulder pain during your workday.

It is recommended to take at least one 10-minute break every hour. During these breaks, stand up, move about and stretch your arms, legs, back, neck and shoulders to relieve tension and muscle aches. 

Also, look away from your computer at least every 20 minutes and gaze at a distant object at least 20 feet away for at least 20 seconds. This relaxes the focusing lens inside the eye to prevent fatigue.

How to Make Virtual Learning Safer For Your Child

The following tips can lessen the impact of screens on your child’s eyes:

  • Reduce overall screen time 
  • Encourage frequent breaks
  • Use accessories that filter blue light (for example, blue light glasses)
  • Schedule regular eye exams

Make Sure Your Child Gets Routine Eye Exams

Children need comprehensive eye exams to assess the health of their eyes, correct their vision and spot potential problems which can affect learning and behavior. 

If you are concerned about the effect of virtual learning and screen time on your child’s eyes, or if you’re due for a checkup, schedule an eye doctor‘s appointment at Village Eye Centre in North Edmonton. 

Q&A

What are blue light glasses?

Blue light glasses, also known as computer glasses, effectively block the transmission of blue light emitted from devices and computer screens. They often include a coating to reduce glare to further reduce eye strain. These glasses can be purchased with or without a prescription. 

What’s the 20-20-20 rule?

If you find yourself gazing at screens all day, whether your computer, smartphone, iPad or television, you’re at risk of experiencing eye strain. So make sure you schedule frequent breaks from your screen and follow the 20-20-20 rule; every 20 minutes, look at something 20 feet away for 20 seconds. And while you’re at it, use this time to get up, walk around, and stretch. 

How to Deal with Contact Lens Discomfort

Do your eyes itch or burn when wearing contact lenses? There are several reasons why you may be experiencing contact lens discomfort. Discover the possible causes behind the problem and see what you can do to relieve your discomfort.

What Causes Contact Lens Discomfort?

Some of the top causes of uncomfortable contacts are:

Dry eyes

Dry eye syndrome is a common condition that arises when your tears can’t keep your eyes sufficiently lubricated due to an imbalance in the tear film. Certain diseases, medications and environmental factors, like high levels of dryness and wind, can cause or contribute to red, itchy or irritated eyes, especially when wearing contacts.

Allergies

Allergens are typically harmless substances that induce an allergic response in certain people. Pollen, mold, dust and pet dander are some of the most common airborne allergens that trigger eye allergies. Cosmetics and certain eye drops, such as artificial tears with preservatives, can also induce eye allergies, which can make contact lens wear uncomfortable.

Corneal irregularities

The cornea at the front of the eye may be irregularly shaped due to astigmatism, keratoconus, eye surgeries (i.e. LASIK or cataract surgery), eye injuries or burns, scarring, corneal ulcers and/or severe dry eye. Irregular corneas often prevent traditional contact lenses from fitting correctly and comfortably.

Symptoms of Contact Lens Discomfort

  • Burning, itchy, stinging eyes
  • Sensation of something being stuck is in the eye
  • Excessive watering or tearing of the eyes
  • Unusual eye secretions
  • Redness of the eyes
  • Reduced sharpness of vision
  • Blurred vision, rainbows, or halos around objects
  • Sensitivity to light

How to Relieve Contact Lens Discomfort

Try Different Contact Lenses

Nowadays, there are many types of contact lenses on the market, including specialty contacts for dry eyes and astigmatism. Meet with our optometrist for a personalized eye exam for contacts.

With the variety of contact lens brands available, switching to a different contact lens may be the simplest answer if you’re experiencing discomfort that isn’t connected to improper fitting or issues with tear production. If your existing lenses fit well but still irritate and dry out your eyes, speak to us about trying a different design or brand of contact lenses, or changing your lens-wearing schedule.

Artificial Tears or Eye Drops

Over-the-counter artificial tears or eye drops are a common way to temporarily relieve contact lens discomfort. However, it’s important to keep in mind that unless prescribed by an eye doctor, they may not be treating the root of the problem.

Moreover, certain eye drops are incompatible with contact lenses, and may damage your contacts or harm your eyes. We also recommend staying away from products that claim to remove redness from your eyes, which temporarily reduce the size of blood vessels to lessen redness, but do not address the underlying cause of the condition, and can actually worsen it over time.

Take Good Care of Your Lenses

Inadequate contact lens care leaves residue on your lenses, which can discomfort, harmful eye infections and inflammation. Below are a few important contact lens hygiene guidelines to follow:

  • Before handling your contact lenses, thoroughly wash and dry your hands.
  • Remove your lenses before showering, bathing or swimming to prevent infection.
  • Do not sleep in your contact lenses (unless they are approved for sleeping).
  • Replace your contact lenses according to the manufacturer’s instructions (e.g., don’t reuse daily wear lenses).
  • Regularly clean your contact lens case and ask your eye doctor when to replace it.
  • Only use a contact lens solution that is appropriate for your lenses.
  • Never reuse or mix contact lens solutions.
  • Schedule regular appointments with your eye doctor.

If you are experiencing discomfort with your contact lenses, get in touch with Village Eye Centre in North Edmonton today. We’ll get to the bottom of the problem and provide effective solutions for all-day comfort.

Q&A

What kinds of contacts are available?

Contact lenses are available in a wide range of materials and replacement schedules. Disposable contact lenses and extended wear contacts are the most convenient for many users.

I’ve already been fitted for contact lenses, so why did my optometrist ask me to come back?

If you’re asked to return a week later, it’s because your optometrist wants to rule out any issues, such as contact lens-related dry eye or irritation.

If it’s been around a year since your last eye checkup, you’ve likely been contacted to check whether your prescription has changed and to evaluate your eye health. The sooner problems are detected and treated, the better the outcome.

Risk Of Overusing Eye Drops

If you find yourself constantly reaching for eye drops, it’s time to start looking into the bigger issue: Why do you need them so often? While they may provide a quick and satisfying fix for irritated or itchy eyes, they don’t focus on what might be causing the irritation to begin with.

Two signs that you’re overusing eye drops: you often exceed the daily recommended dose and/or you view eye drops as a cure rather than a temporary treatment.

Risks of Overusing Eye Drops

When overusing eye drops you can run the risk of:

  • Washing away your natural tears. Artificial tears feel great as they lubricate your eyes and help with insufficient tear production. But overuse can literally wash away the natural moisturizers and your natural tears that protect your eyes.
  • Rebounding. As the effects of the eye drops subside or upon discontinuation of the drops, the original eye symptoms may return stronger than before. This is known as eye rebounding. Eye drops clamp down on the blood vessels in the eye to stop itchiness, which means your sclera isn’t getting the oxygen and nutrients it needs. When you stop using eye drops, or their effects wear off, your eyes may work in overdrive to deliver oxygen to those vessels.
  • Masking a more serious problem. Addressing the symptoms of red, itchy eyes rather than the cause could be more serious than you think.

Conditions That Eye Drops Could Be Masking

Red, itchy eyes are a symptom of several conditions, including:

  • Blepharitis – Red and inflamed eyelids, caused by a fungal or bacterial infection, gland dysfunction, parasites, or dry eye, all of which require treatment beyond over-the-counter eye drops.
  • Eye trauma – Scratching or rubbing your eye can cause blood vessels to break, making the eye itchy and red. Some more serious traumas will require prescription eye drops or surgery.
  • Eye strain – Focusing on work all day and night can cause irritated, tired, and strained eyes.
  • Foreign objects – An eyelash, dust, or something worse could be in your eye. If you have long-term issues with itchy or dry eyes, make sure a foreign body isn’t the culprit.
  • Allergies – Allergies to the environment or pets can cause dry, itchy eyes.
  • Pink eye – A bacterial or viral eye infection, also called conjunctivitis, can cause burning, swelling, and itchiness.
  • Dry eye syndrome – Irritation, redness and itchiness are common symptoms of dry eye syndrome. In severe cases, DES can damage the cornea.

Regardless of why you often use eye drops, the only way to get to the root cause of your symptoms is a thorough eye exam. Don’t cover up the symptoms with eye drops.

If you’re suffering from irritated, dry eyes that haven’t resolved on their own, contact Village Eye Centre in North Edmonton. We can help you find the long-lasting relief you’ve been looking for.

How Sleep Apnea Affects The Eyes

Did you know that some eye conditions are associated with sleep apnea? According to the National Sleep Foundation, more than 18 million Americans have sleep apnea, and Health Canada reports similar prevalence. It’s a sleep disorder where people stop breathing — often multiple times per night — while sleeping.

If you have sleep apnea: it tends to take longer for your tears to be replenished, you’re more likely to have ocular irritation, you have a higher chance of developing floppy eyelids, and you’re at increased risk for glaucoma.

What Is Obstructive Sleep Apnea?

There are different types of sleep apnea. The most common one is obstructive sleep apnea (OSA). During OSA, your airway becomes partially blocked due to relaxed muscles in your nose and throat. This causes apnea (the absence of breathing) or hypopnea (abnormally shallow, slow breathing). It’s twice as common in men, and is more likely to affect people with obesity, hypertension, diabetes or heart disease.

What are the common symptoms of sleep apnea?

Sleep apnea occurs when the muscles in the back of your throat relax too much to allow normal breathing. These temporary breathing lapses cause lower-quality sleep and affect the body’s oxygen supply, which can lead to potentially serious health consequences.

While snoring is a common symptom, not everyone who snores has sleep apnea. Interrupted sleep can cause excessive daytime sleepiness, fatigue, irritability or depression, headaches in the morning, difficulty concentrating and thinking, and a sore throat.

Which Eye Conditions Are Associated With Sleep Apnea?

Glaucoma

Glaucoma occurs when increased pressure within the eye damages the optic nerve, which connects the eye to the brain, leading to vision loss and sometimes blindness. In some cases, it might be due to a drop in blood oxygen levels, which happens when you stop breathing. However, CPAP machines, one of the most common treatments for sleep apnea, can also cause glaucoma.

So, people with sleep apnea — even if it’s being treated — need to get their eyes checked on a regular basis for glaucoma.

Floppy Eyelid Syndrome

Floppy Eyelid Syndrome (FES) is an eye condition where a person has an unusually large and floppy upper eyelid. It can cause eye redness, irritation, discharge, or blurry vision — and over 90% of people with FES also have sleep apnea.

Non-Arteritic Anterior Ischemic Optic Neuropathy

Non-arteritic anterior ischemic optic neuropathy (NAION) is an eye condition that occurs when there is a loss of blood flow to the optic nerve. Patients typically complain of significant vision loss in one eye without any major pain. Approximately 70-80% of patients with NAION have been found to have OSA.

Retinal Vein Occlusion

Also referred to as an ‘eye stroke,’ retinal vein occlusion (RVO) is a blockage of the small veins that carry blood away from the retina. A recent study of 114 RVO patients found that sleep apnea was suspected in 74% of the patients that had previously been diagnosed with RVO.

Other Eye Health Issues Associated With Sleep Apnea

Some other ocular conditions that are more common in patients with sleep apnea include: papilledema, keratoconus, and central serous chorioretinopathy. Furthermore, in addition to glaucoma mentioned above, CPAP machines are associated with dry eye syndrome and bacterial conjunctivitis.

Talk To Your Doc

Get eye exams regularly to rule out eye disorders and prevent potential vision loss, especially if you have been diagnosed with sleep apnea. At Village Eye Centre in North Edmonton we encourage you to share your medical history with us so we can better diagnose and treat any eye conditions or ocular diseases you may have, and help you keep your eyes nice and healthy.

Frequently Asked Questions with Dr. James Evans

Q: What Causes Sleep Apnea?

  • A: Sleep apnea occurs when in-part or completely stop breathing when sleeping. This causes your lungs to strain harder for oxygen, and makes the brain send signals that jerk your body awake to resume proper breathing.

Q: What are the Warning Signs of Sleep Apnea?

  • A: A common sign of sleep apnea is loud snoring. Snoring that is loud enough to disturb the sleep of the patient as well as others around, even across the walls. That said, not everyone who snores suffers from obstructive sleep apnea.

Is Your Face Mask Causing Dry Eye Syndrome?

Dry Eye Syndrome Treatments At Village Eye Centre

Dry Eye Syndrome Treatments At Village Eye Centre

Social distancing and face masks have become the first line of defense in preventing COVID-19. These protective measures are essential to fighting the virus’ spread.

While masks help protect you and others from COVID-19, eye doctors have seen an increase in dry eye cases among those who wear them.

If you’re seeking effective relief, contact Village Eye Centre in North Edmonton as soon as possible. We’ll offer the best solutions for your mask-associated dry eye (also known as “MADE”).

What is Mask-Associated Dry Eye?

Eye doctors have been seeing an increase in dry eye cases at their practice. Patients with existing dry eye syndrome complained that their symptoms worsened when wearing a mask, while other patients complained of first-time symptoms.

Dry eye symptoms result when fast movement of air caused by exhalation leads eye tears to evaporate. A face mask that doesn’t fit securely can push air from the mouth and nose upward onto the eyes.

What is Dry Eye?

Dry eye syndrome causes the eyes to feel gritty, sore, irritated, and dry, and can potentially damage the cornea, if left untreated.

Dry eye syndrome is typically caused by a number of reasons, including health and eye conditions, gender, age, and taking certain medications. Dry weather conditions, indoor heating, air conditioning, and not blinking sufficiently — which is common when staring at a computer screen — can also contribute.

How to Prevent Dry Eye

Here are some easy measures you can take to reduce dry eye:

Mask sure your mask fits correctly

If your mask doesn’t fit properly, your breath will escape from the top of your mask, potentially causing dry eye symptoms. To prevent this, choose masks that fit snugly under your eyes and around the bridge of your nose.

Limit your time in dry environments

If your mask is causing your eyes to feel dry, try to limit your time in windy or dry-air environments, such as windy outdoor weather and air-conditioned rooms.

Keep in mind that people tend to blink less frequently when staring at a screen or reading a book. Blinking provides your eyes with much-needed lubrication, so remember to blink!

Use a warm compress

If your eyes are irritated and sore, dampening a washcloth with warm water and placing it on your closed eyelids for a few minutes can help. The warmth of the water can help stimulate your tear glands to produce more liquid and oil to help keep your eyes lubricated throughout the day.

Use eye drops

Using eye drops can provide the extra lubrication your eyes need to prevent them from drying out. Your eye doctor can advise you on the best drops for your eyes.

Speak to your eye doctor

The best way to minimize your dry eye symptoms—whether caused by a face mask or something else—is to consult your eye doctor, who will examine your eyes and prescribe treatment.

Frequently Asked Questions About Dry Eye Syndrome

Q: Why do my eyes sting when I wear a mask?

  • A: When wearing a loose mask the exhaled air goes into your eyes, which can cause your eyes to sting. So make sure it fits snugly around the bridge of your nose.

Q: What kind of face mask is best to prevent dry eye?

  • A: Ideally, you should wear a face mask with a pliable nose-wire so that it can curve to your cheeks and nose, which reduces air directed toward the eyes.For more information about keeping your eyes healthy while wearing a face mask, contact Village Eye Centre in North Edmonton. We can help determine the underlying cause of your dry eye and offer you the best solution.


Try These 5 Home Remedies For Dry Eye Syndrome

If your eyes sting, burn, or feel scratchy you may have dry eye syndrome (DES), a condition that is usually caused by low-quality or low production of tears.

There are many factors that can cause dry eyes. Smoke and dry air can dry out the eyes, and so can wearing contact lenses, taking certain medications, and spending long periods of time reading a book or looking at a computer screen. In addition, our eyes tend to get drier as we age.

No matter the cause, dry eye syndrome can be extremely uncomfortable, and in severe cases can damage the cornea.

While only Dr. James Evans can diagnose and treat dry eye syndrome, these 5 home remedies may provide some relief.

Warm Compresses

A warm compress will improve oil flow through your eyelid glands and clean your eyelids. You can make them at home with a small face cloth and warm water or purchase compresses at your local pharmacy.

Eyelid Wash

A great form of preventative care is eye washing. Washing your eyes you can keep your tear ducts and eyelids from getting blocked.

To help remove crust from your eyelids and eyelashes and to keep your eyes cleaner, try applying a sting-free shampoo. Some pharmacies sell over-the-counter eyelid and eyelash washes to clean these areas.

Add Omega-3 to Your Diet

Oils are a necessary component of tears, as they add lubrication and reduce evaporation. Dry eye syndrome can result from insufficient oil, so adding omega-3 to your diet can increase the oil in tears.

To increase your omega-3 intake, either take supplements or eat foods that contain high levels of the fatty acid.

Foods that contain Omega-3 include:

  • Chia seeds
  • Flaxseed
  • Palm oil
  • Soybean oil
  • Tuna
  • Salmon
  • Walnuts

Take Frequent Breaks and Blink More

When watching TV, reading, or using the computer many people forget to blink. It’s important to take breaks and blink more to inspire the flow of tears, which helps keep the moisture in your eyes intact. A well-known rule to follow is the 20-20-20 rule. It involves taking breaks at least every 20 minutes to look 20 feet away for 20 seconds — especially when staring at a computer screen or digital device for long periods.

Tweak Your Environment

Environmental factors can cause or exacerbate dry eye symptoms. Heat, dust, smoke, pollution, high winds, and air conditioning all dry out our eyes. Using a cold-mist humidifier and not sitting directly in front of an air conditioner, heater, or fan can help reduce eye irritation.

Stay Hydrated

Last but not least: drink more water! Staying well-hydrated is good for your eyes and is critical for producing healthy tears, clearing out debris, blinking, and seeing comfortably. Be sure you drink lots of water to maintain your eye health, and of course, overall physical well-being.

Home remedies can relieve mild dry eyes but are not a replacement for a comprehensive eye exam. If the symptoms persist or worsen, contact Village Eye Centre in North Edmonton. We are committed to keeping your eyes healthy and your vision clear.

Frequently Asked Questions with Dr. James Evans

Q: Can you request lenses made from glass? Is glass still used for lenses?

  • A: Opticians still sometimes use glass for lenses. However, glass is not used very often because they aren’t as safe. If these glass lenses breaks, they can shatters into many pieces and can injure the eye. Glass lenses are much heavier than plastic lenses, so they can make your eyeglasses less comfortable to wear.

Q: Can a coating be added to eyeglasses to protect them from further scratches?

  • A: A protective coating can’t be added to a lens after it’s scratched. The coating is applied when the lens is manufactured and can’t be put on later.
