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?

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.
