Dry Eye

Bloodshot Eyes – Should You Be Concerned?

You wake up in the morning ready to start your day, only to discover that your eyes are bloodshot. That might not be surprising if you stayed up late to finish a project, had too many drinks at a party or spent time in a smoke-filled room.

But bloodshot eyes can also signal an underlying eye problem. If your eyes appear red or bloodshot, make an appointment with an eye doctor for a comprehensive eye exam to determine the cause and to receive effective treatment.

Why Do I Have Bloodshot Eyes?

When blood rushes to the front of the eye, the tiny red blood vessels on the white of the eye dilate and become visible. This makes the eyes appear red and irritated.

So why do these blood vessels dilate, causing your eyes to look bloodshot?

Bloodshot eyes tend to be caused by:

  • Dry eyes
  • Irritants such as smoke, pollen and perfume
  • Lack of sleep
  • Excessive alcohol consumption
  • Spending too much time in front of the computer

Bloodshot eyes due to lifestyle and environmental irritants may disappear on their own, or you can try to relieve them with over-the-counter eye drops or liquid tears. Lifestyle changes, such as getting more sleep, cutting down on alcohol intake and limiting screen time can often be helpful. If allergies are the culprit, oral antihistamines and antihistamine eye drops may relieve symptoms.

At other times, underlying problems requiring prompt medical attention can cause your eye’s blood vessels to dilate. The following are some of these medical conditions:

Conjunctivitis

You’ve probably heard of “pink eye.” It’s another name for infectious conjunctivitis – an infection of the conjunctiva, the thin membrane covering the eyelid and the front surface of the eye.

There are two types of infectious conjunctivitis – bacterial and viral.

If your child has conjunctivitis, they’re not alone. About 12% of kids get bacterial conjunctivitis every year. This highly contagious condition affects children and adults. In addition to reddish eyes, the following symptoms are associated with conjunctivitis:

  • Bacterial conjunctivitis – irritated eyes, swollen eyelids, eye discharge, crusty eyelids and excessive tearing
  • Viral conjunctivitis – cold or flu-like symptoms, runny nose, fever, itchy eyes, excessive tearing

If you or your child are experiencing these symptoms, it’s important to schedule a prompt appointment with an eye doctor, who can diagnose whether the conjunctivitis is viral, bacterial or due to allergies.

Depending on the diagnosis, your eye doctor will prescribe antibiotic eye drops or creams to treat bacterial conjunctivitis. The viral form may run its course after a few days, but cold compresses and non-prescription eye drops may provide relief.

Dry Eye Syndrome

If your eyes are chronically bloodshot you may have dry eye syndrome (DES). Signs of DES include:

  • Dry, irritated eyes
  • Burning or stinging eyes
  • Discharge from the eyes
  • Light sensitivity
  • A feeling you have something stuck in your eyes
  • Blurred vision
  • Watery eyes

Dry eye syndrome is most commonly caused by a blockage of the tiny meibomian glands in the eyelids. These glands secrete oil that keeps eye moisture from evaporating too quickly. Without the oil, tears dry fast, leaving your eyes feeling dry, itchy and with a bloodshot appearance.

Too much screen time, aging, certain medications such as antihistamines, and medical conditions such as Sjogren’s syndrome can cause dry eye syndrome.

In addition to any medications or in-office treatments your eye doctor recommends, make sure to get plenty of hydration, take frequent breaks from digital screens and use a humidifier in your home.

Uveitis

In addition to bloodshot eyes, if you also experience blurred vision, see floaters or your eyes feel painful, you may have an eye inflammation called uveitis. The causes of uveitis include:

  • Autoimmune or inflammatory condition
  • Infection
  • Medication side effects
  • Cancer (in rare cases)

Unfortunately, uveitis symptoms can often be mistaken for something less serious. That’s the reason it’s important to get an eye exam if your eyes are bloodshot. Left untreated, uveitis can lead to serious conditions such as retinal scarring, cataracts and vision loss.

Depending on the cause and severity, your eye doctor may treat uveitis with prescription eye drops, steroid pills, injections or eye implants.

Eye Injury

It’s vital that all eye injuries receive immediate eye care from an eye doctor.

Even a minor eye injury can cause a big red blotch to form on the white part of the eye (sclera). The cause is a broken blood vessel or a subconjunctival hemorrhage.

Although the appearance of this blood looks severe, and can make the entire white part of the eye appear bright red, a subconjunctival hemorrhage is usually painless and doesn’t cause vision loss. Any time you notice excessive blood on the eye following an eye injury, schedule an appointment with an eye doctor to assess the health of your eye.

Glaucoma

In rare cases, bloodshot eyes may signal the presence of glaucoma – a leading cause of vision loss and blindness.

While some types of glaucoma don’t show symptoms in the early phases, bloodshot eyes can indicate the type of glaucoma that requires immediate medical care. This disease causes damage to the optic nerve due to excessive pressure within the eye. When this pressure suddenly rises, the eye’s blood vessels become dilated and visible, making the eye appear red.

If you have bloodshot eyes and/or have the following risk factors for glaucoma, immediately schedule an appointment with your eye doctor.

  • Family history of glaucoma
  • Aged 60+
  • African American, Asian or Hispanic
  • Diabetes
  • High blood pressure

Q&A With Your Local Optometrist

Can I get bloodshot eyes after LASIK surgery?

LASIK surgery is highly effective minimally invasive laser eye surgery that can correct refractive errors, but like all surgical procedures, it can have side effects. Your eyes may be bloodshot or you could see halos from a few days to three weeks after surgery. Additionally, you may experience other dry eye symptoms. Eye drops and liquid tears can alleviate these symptoms, but if you have any concerns about your eyes following LASIK surgery contact your eye surgeon.

What Should I Expect from a Glaucoma Exam?

If you have a family history and/or other risk factors for glaucoma, and if your eyes look bloodshot, consider scheduling a glaucoma exam. Your eye doctor may perform the following tests:

  • Tonometry – eye pressure test
  • Gonioscopy – to see how fluid is draining out of your eye
  • Vision field test – to examine the functioning of the optic nerve
  • Dilated pupil exam – to detect any damage to the optic nerve
  • Retinal photo or OCT – digital examination of the retina and optic nerve health

Why Is My Eyelid Twitching?

What Is An Eyelid Twitch?

Myokymia, more commonly known as an eyelid twitch, occurs when the eyelid muscles spasm uncontrollably. This sensation is generally felt in either the upper or lower eyelid of one eye.

An eyelid twitch can develop for a number of reasons, and can last anywhere from a few moments to several days, depending on the underlying cause. 

Eyelid twitches are usually nothing to worry about, though persistent eyelid spasms can signal a more serious underlying condition. 

What Causes Eyelid Twitching?

There are a range of factors that could be causing your eyelid to twitch, including:

Stress.

This is the most common cause. Any type of physical or mental stress leads to the release of cortisol, a steroid hormone in the body that acts as a stimulant and puts your body into “flight or fight” mode. It can affect the nervous system in uncharacteristic ways, including making the nerves stimulate your muscles to twitch.

Fatigue.

Have you stayed awake later than usual, or are you juggling work and family commitments? Your eyelid twitch may be a sign that your body is craving a few more hours of rest and shut eye.  

Allergies.

Itchy, watery, irritated eyes can cause eyelid spasms.   

Dry eyes.

Dry, sore eyes may sometimes lead to an eyelid twitch.

Eye strain.

Eye muscle fatigue from prolonged reading or using a digital device can lead to blurry or double vision, dry eyes, headaches and, sometimes, an eyelid twitch.

Caffeine.

Consuming too much caffeine can over-stimulate your mind and body, including the muscles in your eyes.

Alcohol.

Similar to caffeine, excessive alcohol intake can have stimulating effects on your eye muscles.

Nutrient deficiencies.

According to research, a deficiency in vitamins B12 or D, or magnesium, or other electrolyte imbalance can cause an eyelid twitch. 

Blepharospasm.

This rare eye condition is caused by a neurological problem that leads to uncontrollable facial and eyelid spasms that generally worsen over time.These spasms may also cause an increase in blink rate and intensity. 

Neurological disease.

Although uncommon, an eyelid twitch can be a symptom of multiple sclerosis (MS), Parkinson’s disease or Bell’s palsy. 

How to Stop Your Eye Twitch

  • Schedule an eye exam to find out what may be causing your eyelid twitch. Your eye doctor may prescribe glasses to relieve eye strain, or recommend dry eye treatments, Botox injections or oral medication to treat the underlying problem. 
  • Practice stress-relieving activities such as yoga and deep breathing exercises, or simply take some time out of your day to relax.
  • Use eye drops to alleviate eye allergies or dry eye symptoms.
  • Take frequent breaks from the screen and consider wearing computer glasses to reduce eye strain. 
  • Limit caffeine and alcohol consumption to determine if these stimulants may be the cause of your eyelid twitch.
  • Speak with your physician to find out if you can benefit from taking nutritional supplements and to rule out a neurological disorder, especially if other symptoms are present.

 Although an eye twitch is generally not a cause for concern, if it persists for longer than a few days or you notice any changes to your vision, contact Dr. Samantha Bourdeau at Ray Dahl Optical & Optometrists today to schedule an eye exam. 

Q & A

What is dry eye syndrome?

Dry eye syndrome (DES) is a chronic condition that occurs when your eyes don’t produce enough tears or the quality of your tear film is compromised. This results in a range of symptoms that may include dry, itchy, irritated eyes, and sometimes eye twitches. While mild DES can often be alleviated temporarily with over-the-counter lubricating eye drops, moderate to severe DES generally requires specialized in-office treatments.

How can I relieve eye strain after prolonged screen time?

Digital eye strain, also known as computer vision syndrome, can cause a host of uncomfortable symptoms, including headaches, eye fatigue, dry eyes and blurry vision. Computer vision syndrome may cause your eyelid to twitch. 

If limiting screen time isn’t practical on a daily basis, try to follow the 20-20-20 rule: every 20 minutes, look at something around 20 feet away for at least 20 seconds. It is also important to remember to blink frequently and to close your eyes completely. Lastly, speak to your optometrist about wearing computer glasses while you work, as they are designed to eliminate glare from the screen, and reduce eye strain.

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 Ray Dahl Optical & Optometrists in Sidney. 

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 Ray Dahl Optical & Optometrists in Sidney 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 Ray Dahl Optical & Optometrists in Sidney. We can help you find the long-lasting relief you’ve been looking for.

Why You Need to Make Eye Care a Part of Your Health Care Plan!

Regular physical exams and screenings for disease have become an integral part of routine health care for many people. Yet, what about eye care? Do you remember to visit your eye doctor yearly for eye care services, or do you only go if you have a problem with your vision?

Many people neglect to include eye care in their regular health care plan. This is a mistake! Regular eye exams can provide your eye doctor with a chance to help you correct vision changes, as well as identify any signs of ocular disease at a very early stage.

Vision correction

When you wear glasses or contact lenses, yearly eye exams are important for detecting any changes in your vision that could lead to disturbing symptoms, such as headaches, eye strain, and double vision. Why wait until you experience painful symptoms?

Your eye doctor will assess your visual acuity and visual skills thoroughly to ensure your prescription is up to date. Vision changes as you age, and conditions such as presbyopia are normal. A pair of reading glasses, bifocals or multifocal progressives can resolve this problem easily.

Also, a variety of new surgical procedures and treatments are available to correct vision. If you’re interested in seeing clearly without prescription eyewear, ask your eye doctor about the latest eye care services on offer!

Keep an eye on eye health

As you reach your 60s and older, it’s important to be informed about different warning signs of age-related ocular health diseases and conditions that can lead to vision loss. Many eye diseases present no early warning signs, so an eye exam by a qualified eye doctor is the only dependable way to diagnose or rule out these problems!

Vision disorders to watch out for include:

  • Age-related macular degeneration – this condition affects the macula, leading to a loss of central vision.
  • Cataracts – when the normally clear lens of your eye becomes cloudy, which can weaken your sensitivity to contrast, dim colors, and increase sensitivity to glare.
  • Diabetic retinopathy – this can occur in people with any type of diabetes; it’s caused by damage to the small blood vessels that supply oxygen to the retina and can lead to retinal inflammation, blurry vision, and blindness.
  • Dry eye syndrome – this condition is characterized by an inadequate quantity of tears or a poor tear composition, so the eye is lubricated well.
  • Glaucoma – this refers to a group of eye diseases that can damage the optic nerve, leading to permanent vision loss.
  • Retinal Detachment – a tearing or separation of the retina from underlying eye tissue.

Remember, the earlier these diseases are detected – the more effectively they can be treated, before you suffer permanent damage to your vision.

Primary eye care is vital for your health. To protect your lasting vision, take advantage of all the preventive, rehabilitative, and curative eye care services your eye doctor has to offer!

  • Is it possible to prevent Macular Degeneration?

    Doctors aren’t sure how to prevent macular degeneration. Research suggests that ultraviolet light (and possibly blue light) factors into the problem, so sunglasses could be very beneficial.

  • What are cataracts and how can they be treated?

    Cataracts are a clouding of the lens inside the eye. They are common with age, certain medications and medical conditions. Patients usually feel like they are looking through a dirty window, cannot see colours the way they used to or have increased difficulty with glare. Currently, the treatment is surgery to remove the cloudy lens. Stay tuned for medical advances in cataract treatment in the future!

  • What is diabetic retinopathy?

    Diabetic retinopathy is a condition which can occur at any stage or type of diabetes. In fact, many times diabetes is identified during an eye exam in a person who never suspected they may have diabetes. It is caused by damage to the very delicate blood vessels within the retina. Over time, these blood vessels may start to leak blood and fluid into the retina or other areas of the eye. If the condition progresses, new vessels may begin to grow within the retina, which places the retina at risk of additional and sometimes sudden complications including internal bleeds and retinal detachment.

  • Are there some every day activities that can cause Dry Eye?

    Generally those that suffer with allergies, or have systemic inflammatory diseases like arthritis and sjogrens’, or those who use the computer or digital devices often and even contact lens wearers tend to be more susceptible to dry eye symptoms.

9 Eye-Healthy Habits for Computer Users

As Covid-19 kept all of us homebound for long periods, the gaming industry grew by leaps and bounds. Then, even when countries began to reopen and jumpstart their economy, nobody abandoned their video games. In fact, sales of video games experienced a 35% jump.

Impact of Gaming on Eye Health

What are some of the effects of this rising role of gaming in our lifestyle? It translates directly into increased screen time, which our optometrist near you points out is linked to a variety of negative effects on eye health. For some of us, the digital era has turned our days into an endless view of screens. As a result, many people suffer the symptoms of computer vision syndrome, such as:

  • Less blinking, leading to dry eyes
  • Blurry vision
  • Eye irritation, burning
  • Eye fatigue and strain
  • Headaches

While it’s unlikely that excessive screen time can cause irreversible damage to your eyes, dry eye syndrome and eye strain can worsen gradually – leading to painful vision and a decreased quality of life.

How to Preserve Healthy Vision with Computer Use

To help keep your vision healthy, despite all the long periods spent at a computer, the eye doctor near you recommends the following habits:

  1. The 20-20-20 Rule Instead of staring for hours on end at a computer screen, take regular breaks to rest your eyes. Follow this rule – every 20 minutes, move your eyes to look at an object 20 feet away for at least 20 seconds.
  2. Set Up Good Lighting Glare and other visual disturbances can make it harder to read text, which can lead to eye strain. By angling your monitor away from light sources and windows, you can eliminate glare from the screen.
  3. Adjust Screen Brightness When adjusting the lighting in your office or home is too tricky, change the monitor’s brightness instead. Rule of thumb – make it as bright as the room you are in.
  4. Take Eye Health Vitamins Supplements such as omega-3 fatty acids are a great addition to your eye care routine, helping to fortify your eyes against problems.
  5. Block Blue Light You can wear specialized blue light glasses to shield your eyes from harmful blue light emitted by digital devices, or install a blue light filter on your digital screen. Not only will these protective devices help promote quality eye health, but they can also help you sleep better at night.
  6. Eat Nutritiously A healthy, balanced diet will keep your body at its peak and improve vision to boot. Some good food choices include cold-water fish, like salmon, tuna and sardines, nuts, eggs, legumes, whole grains, berries, leafy greens, and citrus fruits.
  7. Increase Font Size A small font size can cause you to squint and hunch over to see the screen clearly. By enlarging the font, you can avoid the discomfort caused by this position.
  8. Sleep Enough Not getting enough sleep can lead to eye fatigue, which interferes with your everyday life and productivity.
  9. Visit Our Eye Clinic Near You for Regular Eye Exams Getting your eyes checked is essential for proper eye health. It’s the only reliable way to detect or rule out an eye disease or condition that requires early treatment.

Many eye diseases can be quickly and easily diagnosed during a Comprehensive eye exam, Pediatric eye exam and Contact lens eye exam. If you were diagnosed with an eye disease, such as Cataracts, Astigmatism, Pink Eye or conjunctivitis Myopia or Nearsightedness , Glaucoma, Macular degeneration, Diabetic retinopathy, or Dry eye, you may be overwhelmed by the diagnosis and confused about what happens next. Will you need medications or surgery – now or in the future? Is LASIK eye and vision surgery an option for you ? Our Sidney eye doctor is always ready to answer your questions about eye disease and Contact lenses.

    • Why do I need to have my eyes examined by an Optometrist if the nurse at my last physical exam says I can see 20/20?

      The nurse performed a “sight test”, when you come to see your Optometrist we perform an “Eye Exam”. A “sight test” only measures if you can see 20/20. An “Eye Exam” measures all aspects of visual function: sight (or visual acuity), binocular vision function (the ability of the eyes to work together), visual pathway integrity, and the overall health of your eyes. Seeing 20/20 is an important part of the overall function of your eyes; however, just because you can see 20/20 does not necessarily mean your eyes are 100% healthy. There are many conditions that exist in which someone can still see 20/20. To name just a few examples: Diabetic Retinopathy, Glaucoma, and even Retinal tears or detachments (if the macula is unaffected). I recommend having a full eye exam every 1-2 years, even if you are in good health and feel like you don’t need glasses.

    • Does reading my smartphone or tablet in the dark damage my eyes?

      Reading from a tablet or smartphone in the dark is okay for your eyes, as long as this is not for a long period of time. There is good lighting from these devices, with good contrast. There is, however, the blue light emitted from these devices. Blue light is a short wavelength light, with high energy that may cause damage to the structures of the eye if exposed for a long period of time. As well, studies have shown this blue light can disrupt melatonin production which is required for a healthy sleep cycle. Doctors of Optometry recommend limiting screen use during the last hour before bedtime.

    • What is blue light and why is it dangerous?

      Blue light is part of visible light and close to UV on the light spectrum. It is naturally produced by the sun, used in fluorescent light bulbs and emitted by LED screens on computer monitors, tablets, and smartphones. The eyes’ natural filters do not block blue light and chronic exposure can cause age-related macular degeneration. Evidence also shows that blue light exposure can lead to sleep problems.’

    • My eyes are always burning and tired, what is causing this and what can I do about it?

      These are often signs of dry eye syndrome, a very common condition that affects many people over time. Women are generally more prone to developing these symptoms and aging is often a cause as well. Dryness of our eyes is often due to a decrease in the oil production in our eyelid glands which causes the surface of the eye to become irritated. Certain medications and health issues can also contribute to dryness. There is no true cure for dryness but many treatments are available such as the use of artificial tears, nutritional supplements incorporating Omega 3, prescription medications such as Restasis, and eyelid hygiene. No single treatment works for every individual so we customize treatments for each person and their specific condition.

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.

Frequently Asked Questions with Dr. Samantha Bourdeau

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.

What Is Prevent Blindness?

Founded in 1908, Prevent Blindness was established by volunteers to decrease the amount of preventable blindness in children. They helped to almost eliminate a condition called ophthalmia neonatorum, a leading cause of blindness in infants at the time.

How do masks lead to dry eyes?

If you’re wearing a mask and eyeglasses, every time you breathe it fogs up your lenses. Then they defog, only to fog up again with your next breath. Steamed-up glasses and the onset of dry eye symptoms is an emerging condition to be aware of. The main reason for promoting awareness of MADE is not to encourage anyone to stop wearing a mask, but rather, it’s to help people manage the eye irritation that may result – while continuing to don face masks.

When you breathe, you expel air over the top of your mask. This air flows over the surface of your eyes and can dry out the tear film that coats and lubricates your eye surface. It also speeds evaporation of tears.

In general, our eye doctor near you has found that mask wearing doesn’t trigger the onset of dry eye syndrome in people who don’t have it. Instead, it can worsen symptoms in people who already have the condition or are at high risk for it – such as people who spend a lot of time staring at computer screens. Nowadays, with all the working-from-home and Zoom meetings that occur, most people fall into the category of “at risk” for dry eye syndrome.

How can you prevent your mask from causing dry eye irritation?

  • Make sure your mask fits properly. A poorly fitting face covering increases the chances that exhaled air escapes from the top opening and flows over your eyes. Push the metal strip at the top margin of your mask so it fits snugly over the contour of your nose and cheekbones, blocking airflow.
  • Avoid rubbing your eyes. This habit can lead to a long list of problems, including micro-scratches in your cornea and swelling that can exacerbate the symptoms.
  • Don’t ignore dry eye symptoms. Pay attention to how your eyes feel and seek effective treatment, such as lubricating eye drops, from our optometrist near you.
