What To Do if a Mosquito Bites Your Eyelid

Many of us spend the warm weather outdoors, barbecuing, camping, hiking, swimming. Although the itchy mosquito bites are typically associated with summer, mosquitos can be relentless and be a major pest, in the spring and even into the fall.

Why do Mosquitoes Bite?

Mosquitoes are small flying insects, but they don’t actually “bite”. They pierce the skin to reach a person’s blood vessels to access a source of protein for the female’s eggs. Male mosquitoes do not consume blood.

While most mosquitoes are harmless, others may carry dangerous diseases, such as malaria, in certain parts of the world. In rare cases, mosquito bites can cause other complications.

What does a mosquito bite on the eyelid look like?

A mosquito bite on the eyelid typically causes redness and inflammation of the eyelid and the surrounding area.

Since the tissue around the eye is loose, fluid accumulation and inflammation following an insect bite is common. In severe cases, it can even inhibit the eye from opening, especially after lying down, as the fluid gravitates to that area.

The skin around the eye is sensitive, so the itching and discomfort from a bite on the eyelid may feel particularly intense. Rest assured that most of the time the itchiness lasts only a few days, but try to avoid rubbing your eyes as it can exacerbate the swelling and irritation.

Are Mosquito Bites on the Eyelid Dangerous?

Usually not, but they can cause severe itching and swelling.

Young children are at a higher risk for acute swelling from a mosquito bite, as they tend to have a stronger immune response than adults do. While your child’s eye may look concerning, the inflammation should naturally subside within a few days.

Signs of an infected mosquito bite

Although uncommon, there are instances when a mosquito bite can become infected and require medical attention. Here are some signs to look out for:

  • An eyelid that develops a deep red appearance
  • An eyelid that is hot and hard to the touch
  • Discharge from the eye
  • Intense pain around the eye
  • Swelling doesn’t subside after 2-3 days

Sometimes, if the bite becomes infected, the infection will spread to the second eye and symptoms will likely be apparent in both eyelids.

If you’re experiencing any of these symptoms or if your vision is affected by your swollen eyelid, contact us for an eye exam and to determine the best course of treatment. If the eyelid isn’t infected, the following home remedies may help.

Home Remedies to Reduce Eyelid Discomfort and Swelling

Try these tips to help relieve your discomfort and promote healing.

  1. Cold Compresses. Place a cold, wet compress on your eye for around 20 minutes, 2-3 times per day to reduce the swelling and numb the itchiness. Be sure that the compress is not too cold as it can damage the skin around your eye.
  2. Allergy Medicine. Take an antihistamine, either in liquid or tablet form, to reduce itching and inflammation. Be sure to read the directions on the bottle for proper dosage information.
  3. Eye Drops. Eye drops can help further reduce inflammation and provide additional relief, especially if your vision is being affected. Vasoconstrictor eye drops are generally recommended to reduce the swelling of the blood vessels in the eyes. These drops should be used sparingly as they can cause a rebound effect – making the eyes red once they heal. It’s best to consult with your eye doctor before using any eye drops, just to be sure.

Most mosquito bites will heal on their own without any need for additional treatment. However, the eyelid is a sensitive area and may require special care to speed up the healing process.

Q&A

What is an eye infection?

An eye infection is a condition in which viruses, bacteria or other microbial agents attack the eye, causing itchy and red eyes. The infection can also affect the eyelid, cornea, and conjunctiva (the thin area that covers the inside of the eyelids and outer part of the eye).

​​What are the typical symptoms of an eye infection?

Usually people with an eye infection experience at least one of the following:

Eye pain, persistent itching, grittiness, sensitivity to light, watery eyes, fluid discharge, blurred vision, irritation, swelling and dryness. These symptoms can often be confounded with dry eye disease. To determine the source of the issue and receive optimal treatment, contact Corktown Eyecare today.

6 Ways To Maintain Eye Health If You’re Over 50

Aging and certain lifestyle choices can affect your vision, especially if you’re in your 50’s and up. While it’s normal for your eyes and vision to change, there are certain actions you can take to protect your sight.

6 Tips for 50+ Eye Health

  1. Eat Well

    A well-balanced diet helps maintain a healthy body including healthy eyes, and reduces your odds of developing some very serious eye diseases. Nutrients and nutritious foods, which help prevent vision loss include:

    • Vitamin A: Carrots, spinach, kale, egg yolks, dairy products
    • Vitamin C: Citrus fruits and juices, broccoli, potatoes, green peppers
    • Vitamin E: Whole grains, eggs, sunflower seeds, vegetable oils
    • Fatty Acids: Coldwater fish, such as mackerel, rainbow trout and salmon; corn oil, sunflower oil
    • Lutein: Kale, spinach, broccoli, brussels sprouts, corn
    • Zinc: Poultry, meat, fish, dairy products, whole grains
  1. Quit Smoking

Smoking can significantly increase the chances of developing age-related macular degeneration and cataracts, as well as diabetic retinopathy in diabetics. So if you’re a smoker, the sooner you quit, the better.

  1. Exercise

Exercising for at least 20 minutes a day is great for your whole body, including your eyes, by increasing blood flow to the optic nerve and retina! It isn’t necessary to engage in strenuous exercise—in fact, a brisk walk will suffice.

  1. Protect Your Eyes

Sunglasses

Protecting your eyes from ultraviolet rays with UV-blocking sunglasses can slow down the development of cataracts, prevent sun damage to your retina, and lower the risk of skin cancer near your eyes.

Protective eyewear

Another way to protect your eyes is to wear protective eyewear. If you play sports or work with materials such as wood, glass or metal, protective eyewear can shield your eyes from splinters and shards, as well as fast-moving objects like balls and hockey pucks.

  1. Give Your Eyes a Rest

If you spend a lot of time reading, driving or looking at digital devices, you may develop eye strain and eye fatigue. By implementing the 20-20-20 rule, especially during prolonged computer or smartphone use, you can give your eyes some much-needed rest. All you need to do is this: every 20 minutes look at something 20 feet away for at least 20 seconds.

  1. Have Regular Eye Exams

And finally, a comprehensive eye exam is crucial, as it can detect eye conditions that don’t display any symptoms until vision loss has already occurred.

These conditions include:

    • Age-Related Macular Degeneration
    • Cataracts
    • Glaucoma
    • Diabetic Retinopathy

When detected early, treatment can often prevent permanent vision loss or even blindness. Less serious and more common, presbyopia or age-related farsightedness, develops with age, and simply updating your prescription for glasses or contact lenses at your routine eye checkup can keep you enjoying the arm’s-length activities you love.

Age-related vision changes can be challenging, both emotionally and physically. However, some of these can be mitigated by implementing the tips above. Schedule an eye exam with Corktown Eyecare in Toronto to check your eye health today!

Q&A

How does aging affect your eyes?

Aging causes changes in every part of your body, including your eyes. As you age, the lens inside your eye begins to harden, which leads to presbyopia (age-related farsightedness). This makes it more difficult for your eyes to focus on near objects and tasks like reading. Other common age-related eye problems include:

  • Age-Related Macular Degeneration
  • Cataracts
  • Glaucoma
  • Diabetic Retinopathy
  • Dry Eyes
  • Floaters
  • Changes to Peripheral Vision

Can I do anything about my chances of vision loss?

It is estimated that half of all visual impairment and blindness can be prevented through early diagnosis and treatment. So make sure you get regular eye exams to ensure that all is in check.

Back-To-School: Why [Eye_Exams] Are More Important Than Ever

Since the onset of COVID-19, many children have been learning remotely through distance learning programs. While parents are concerned about their children falling behind academically, eye doctors are concerned that undiagnosed vision problems may impact the child’s school performance.

Undetected vision problems may hinder a child’s ability to learn. That’s why eye doctors strongly recommend that children undergo a thorough eye exam before the new school year begins.

While it’s tempting to rely on vision screenings provided by schools, these superficial visual acuity tests can identify only a limited number of eyesight problems. Only a comprehensive eye exam conducted by an eye doctor can accurately diagnose and address a wide range of problems related to vision and eye health.

Why Are Eye Exams Important?

Up to 80% of children’s learning is visual, so even the slightest vision problem can have a negative impact on their academic achievement. Taking a child in for an eye exam once a year will allow your eye doctor to detect and correct refractive errors like myopia (nearsightedness), hyperopia (farsightedness) and astigmatism, and check their visual skills, such as convergence insufficiency, binocular vision, focusing and more.

Comprehensive eye exams are the best way to detect mild and serious eye health conditions. Routine eye exams are especially important for children with a family history of eye health problems.

How Is Vision Affected By Online Learning?

The amount of time children spend looking at digital screens was already a concern in the pre-pandemic era—but the COVID pandemic has only exacerbated the issue. According to the Indian Journal of Ophthalmology, children spent twice as much time on screens during COVID-related closures than they did prior to the pandemic.

For one thing, spending prolonged periods of time on digital devices forces the eyes to work harder, making children (and adults) more susceptible to digital eye strain, one of the hallmark symptoms of computer vision syndrome. People who spend 2 or more consecutive hours staring at a screen are at higher risk of developing this condition.

Some computer vision syndrome symptoms include:

  • Blurred vision
  • Dry eyes
  • Eye fatigue
  • Eye pain
  • Headaches
  • Neck and shoulder pain

These symptoms can be caused by a combination of the following factors:

  • Glare and reflections from the screen
  • Excessive time looking at a screen
  • Poor lighting
  • Poor posture
  • Screen brightness
  • Undetected vision problems

In addition to digital eye strain, several studies have found that children who spend many hours indoors doing “near work” — writing, reading and looking at computers and other digital devices — have a higher rate of myopia progression.

A study published in the American Academy of Ophthalmology’s professional journal, Ophthalmology, found that first-graders who spent at least 11 hours per week playing outside in the sunshine experienced slower myopia progression. Some researchers think that exposure to sunlight and looking at distant objects while playing outdoors might help decrease myopia progression.

While regular eye exams are essential for every member of the family, they’re especially important for those who spend a good portion of their day in front of a screen.

Don’t put off your child’s annual eye exam. Schedule an appointment with Corktown Eyecare in Toronto today!

Q&A

1. At what age should a child have an eye exam?

According to the American and Canadian Optometric Associations, it’s recommended for a child to have their first eye exam between 6-12 months of age.

Before a child starts school, they should undergo an eye exam, and every one to two years after that, based on their eye doctor‘s recommendation.

2. Does my child need an eye exam if they passed the school vision screening?

Yes! School vision screenings are superficial eye evaluations designed to diagnose a limited number of vision problems like myopia. They do not check for visual skills and other problems that may hinder your child’s academic success.

Your eye doctor will evaluate your child’s vision and eye health, along with visual abilities, including depth perception and eye tracking, to let you know whether your child’s eyes are “school-ready.”

 

What Eye Drops Are Best For My Eyes?

Are you suffering from red, irritated and scratchy eyes? Do you feel like you have something stuck in your eyes? These are hallmark symptoms of dry eye syndrome, a condition that occurs when your eyes are not properly lubricated due to insufficient tear production, blocked glands, or unbalanced tear composition.

The symptoms can be so unpleasant that many rush to the nearest pharmacy to find the perfect eye drops that will offer them the relief they need so that they can get back to focusing on other things.

However, seeking the ideal artificial tears to relieve dry eyes can be a daunting process. The eye drops shelf at the drug store offers so many options that it’s hard to know which ones are right for you. What’s more, some can actually make your symptoms worse.

Not all eye drops are created equal—currently, there are 6 main categories of artificial tears available over the counter. Choosing the artificial tears based on your specific needs can help narrow your options.

The 6 Types of Eye Drops / Artificial Tears

Preserved Artificial Tears

Preserved artificial tears contain added preservatives to maintain a very long shelf and keep bacteria at bay once the bottle is opened. Unfortunately, it also causes inflammatory dry eye disease, meibomian gland dysfunction and an allergic reaction in those who are sensitive, leading to redness, irritation and inflammation. While these drops may offer temporary relief, long term they can do more harm than good. Moreover, the preservatives may leave residue on contact lenses.

Preservative-Free Artificial Tears

Preservative-free artificial tears are great for contact lens wearers as they don’t cause any preservative build-up on the lenses. They are also suitable for those with sensitive eyes since they contain fewer ingredients that can cause irritation.

Preservative-free eye drops typically come in a box of 28 to 30 small vials that fit in a pocket or purse.

To use these drops, just pop the top off and insert the drops into your eyes. Some of these vials can be re-capped to allow you to continue to use the vial for up to 24 hours, but not longer. Refrigerate opened vials between uses to prevent any bacterial growth.

Oil-Based Artificial Tears

Oil-based tears come in preserved and preservative-free versions. These are thicker than traditional eye drops, as they contain an oil-based formulation. The oil helps prevent the watery portion of the tears from evaporating too quickly.

If you suffer from moderate or severe dry eye, oil-based artificial tears may be a great option. However, they’re not recommended for contact lens wearers, as the oils may stick to the surface of the lenses, making it difficult to keep them clean.

Eye Drop Spray or Mist

These sprays are preservative-free and are used to relieve dryness and irritation in both the eyes and eyelids. They’re easy to use, especially for those who struggle to insert drops into their eyes.

To use the spray, just close your eyes and spray onto your closed eyelids. Once you blink, the tears will slide into your eyes.

Don’t use the spray if you’re wearing makeup, lotions, or creams on your eyelids, as it can cause the makeup or lotion to enter your eye.

Artificial Tear Gel

Artificial tear gel adds a thick coating of tears and can be used at any time of the day or night. However, the thicker consistency of the gel drop may blur your vision for several minutes.

The gel is applied in the same way as eye drops. It effectively soothes the eyes and provides extended relief for both moderate to severe dry eye.

Most artificial tear gels contain preservatives, so they can only be used up to 4 times a day, and usually they are not safe for contact lens wearers.

Artificial Tear Ointment

Dry eye ointments are thick and coat the front of your eye. They’re usually used 1 to 2 times daily as needed. It may be best to use them at bedtime, as it will blur your vision.

Get Dry Eye Relief Today!

Artificial tears may be a good way to temporarily relieve eye dryness. However, using the wrong type of eye drops can be worse than not using any drops at all. So be sure to consult your eye doctor before you get eye drops.

Keep in mind that eye drops don’t address the root cause of dry eyes; they just provide temporary respite from the uncomfortable dry eye symptoms. Only an eye doctor can examine your eyes to determine the underlying cause of your symptoms and recommend the best treatment for your unique case of dry eye.

Schedule an appointment with Corktown Eyecare in Toronto to learn more about dry eye syndrome and to find out which treatment is best for you.

Q&A

Frequently Asked Questions with Sanjay Vakani, O.D.

Q: What is dry eye syndrome?

    • A: Dry eye syndrome is a condition where your eyes either produce low-quality tears or don’t produce enough tears to keep your eyes hydrated. This may be due to certain diseases (like diabetes or other autoimmune diseases), aging, allergies, hormonal changes, smoking, poor air quality, medications and the environment.

    Q: What are the symptoms of dry eye syndrome?

          • A: Dry eye syndrome can cause a wide range of symptoms including:Itchy eyes
            A feeling that there is grit or debris in the eye
            Blurred vision
            Burning sensation
            Dryness
            Irritation
            Sensitivity to light and glare

      Q: Artificial Tears

                • A: Artificial tears are drops used to lubricate dry eyes. These drops help maintain moisture on the surface of your eyes. Artificial tears are available without a prescription from your optometrist. There is no one brand works best for every form of dry eyes. Aside lubricating the surface of your eyes, artificial tears can also promote healing of the eyes. Additionally, some types of drops work to decrease the evaporation of tears from the surface of your eyes. Artificial tears may also contain thickening agents, which keep the solution on the surface of your eyes longer.

      Why Are Blue Eyes More Sensitive To Light?

      Did you know that blue eyes don’t contain any blue pigment? They appear blue due to how the light reacts with the structures of the iris.

      In fact, the top layer of a blue iris doesn’t contain any pigment at all. This lack of pigment is the reason that blue-eyed people may be more sensitive to bright light and have a greater need to wear sunglasses than their brown-eyed counterparts.

      Why Do Your Eyes Need Sun Protection?

      Eyes of all colors need shielding from the sun’s harmful ultraviolet (UV) rays. Exposure to UV light can contribute to the formation of short-term and long-term eye conditions such as corneal sunburn and macular degeneration.

      That’s why it’s so important to choose high-quality sunwear with 100% UV blocking lenses, and to throw on a sun hat for an added layer of protection.

      UV protection is important for individuals of all ages—especially children—who are more susceptible than adults to the sun’s harmful rays, and tend to spend more time outdoors. It is estimated that up to 80% of a person’s lifetime exposure to UV rays happens before the age of 18.

      Why are Blue Eyes More Sensitive to Light?

      Lighter colored eyes like blue, hazel and green have less of a pigment called ‘melanin’ than brown eyes do.

      Melanin helps protect the retina from UV damage and blue light, putting those with blue eyes at a higher risk of developing UV-related eye damage.

      If you have blue eyes, you may have experienced this first-hand. Bright light may be uncomfortable or you may want to reach for your shades as soon as you leave the house on a sunny day.

      That’s why optometrists urge blue-eyed patients to be particularly vigilant about UV protection, so as to mitigate their chances of developing eye disease and other complications.

      How We Can Help

      Whether you have blue eyes or not, sunglasses are an important part of keeping your eyes healthy for a lifetime.

      At Corktown Eyecare, we’ll be happy to advise on the perfect high-quality and protective pair of sunglasses to suit your needs and personal style.

      Frequently Asked Questions with Sanjay Vakani, O.D.

      Q 1: Should I wear sunglasses even when it’s not sunny outside?

      • A: Yes! You should wear your sunglasses whenever outdoors during the day, even on an overcast, winter day. UV light can pass through clouds and reflect off surfaces like car windows and pavement.

      Q 2: What type of sunglasses are the most suitable for blue eyes?

      • A: The most protective sunglasses are wraparound sunglasses that protect the eyes from every angle. You can also opt for photochromic lenses, which offer total UV protection but only become tinted when exposed to outdoor sunlight, and turn clear when you come indoors again. Your optometrist can help you choose the best lens and frame options for your needs and lifestyle.

      Childhood Myopia Is in Crisis Mode on a Global Scale

      When it comes to the prevalence of myopia (nearsightedness), the statistics are staggering. By 2050, nearly half of the world’s population—about 5 billion people—will be myopic. Below are a few useful tips to help you prevent your child from being part of that statistic.

      What Is Myopia?

      Myopia occurs when the eye elongates, causing light rays to focus in front of the light-sensitive retina rather than directly on it, while looking at something far away. So, people with nearsightedness perceive distant objects as blurred while close-up objects can remain clear.

      Myopia tends to develop during childhood, when the eyeballs rapidly grow (along with the rest of the body), mainly between the ages of 8-18. It can worsen slowly or quickly, but it is not simply an inconvenience. People with progressive myopia are more likely to develop serious eye diseases like cataracts, retinal detachment, macular degeneration and glaucoma later in life—conditions which may lead to permanent loss of vision and even blindness.

      How To Know Whether Your Child Is Myopic

      Below are some telltale signs to watch for:

      • Blurred distance vision – Objects in the distance are blurred; kids may complain that they can’t see the board
      • Headaches – When myopia isn’t corrected, it can cause eye strain and headaches.
      • Head tilting or squinting – If your child squints or tilts his or her head while watching TV, for example, it may be a symptom of myopia.
      • Looking at objects too closely – If you notice your child moving closer to the TV or squinting as they try to see the writing on the board, it may indicate myopia.

      What Parents Can Do to Slow Their Child’s Myopia Progression

      • Encourage your child to go outdoors for at least 90 minutes a day, preferably in the sunshine. Studies show that playing outdoors reduces the risk of developing myopia and slows its progression.
      • Limit the amount of time your child spends staring at a screen, reading and doing close work such as homework.
      • When your child uses a digital screen, make sure that it isn’t too close to the face.
      • Teach the 20-20-20 rule: During screen time, take a break every 20 minutes to look at an object across the room or out the window about 20 feet away, for at least 20 seconds.
      Frequently Asked Questions with Sanjay Vakani, O.D.

      Q: How is myopia diagnosed?

      • A: Your child’s eye doctor will perform a thorough pediatric eye exam to diagnose myopia, which often includes a visual acuity test, where the eye doctor will use an eye chart made up of letters of varied sizes. If the test results indicate myopia, then the optometrist may shine a light into their eyes and evaluate the reflection off the retina to determine the degree of refractive error for their prescription.

      Q: Can myopia lead to blindness?

      • A: High myopia may increase your child’s risk of developing more serious eye conditions later in life, such as cataracts, retinal detachment and glaucoma. Left untreated, high myopia complications can sometimes lead to blindness—which is why routine eye exams are critical.

      Are You Susceptible To Vision Loss?

      Vision loss is more common than you may think! In fact, it’s among the most prevalent disabilities in adults and children. Knowing what puts you at risk of developing vision loss is important and can help you to be proactive about caring for your eyes.

      Below, we’ll explore the most common causes of vision loss and the risk factors associated with each.

      Spreading awareness and education about visual health is just one way that our eye doctors near you can help. To schedule your comprehensive eye exam, call us today.

      Common Causes of Vision Loss

      Glaucoma

      Glaucoma is a group of eye diseases caused by a buildup of pressure within the eye. Too much inner-eye pressure can damage the optic nerve and lead to vision loss.

      Since symptoms don’t usually manifest in the early stages of glaucoma, getting regular eye exams is all the more crucial. Advanced or rapidly progressing glaucoma can show a variety of symptoms, such as blurred vision, headache, severe eye pain and redness, seeing halos around lights, and nausea.

      Risk factors for developing glaucoma include:

      • Being 60 years or older
      • Family history of glaucoma
      • African, Asian, or Hispanic descent
      • High myopia (nearsightedness) or hyperopia (farsightedness)
      • Previous eye injury or certain eye surgeries
      • Certain medications, like corticosteroids
      • Thin corneas
      • Certain medical conditions, like diabetes, hypertension, heart disease, and sickle-cell anemia

      Cataracts

      Cataracts occur when the eye’s lens becomes cloudy. A healthy lens is clear and allows light to pass through it undisturbed.

      Common cataract symptoms include cloudy or blurred vision, difficulty seeing at night, light sensitivity, double vision in the affected eye, and seeing colors as faded or yellowish.

      Risk factors for developing cataracts include:

      • Aging
      • Diabetes
      • Hypertension
      • Smoking
      • Previous eye surgery, injury, or inflammation
      • Alcoholism
      • Extended use of corticosteroids

      Age-Related Macular Degeneration (AMD)

      AMD is the leading cause of severe vision loss in adults over the age of 60. It occurs when the macula (the small central portion of the retina, which is responsible for sharp, colorful, central vision) begins to wear down.

      Early stages of AMD usually go unnoticed, but later stages of the disease can produce symptoms like blurred vision, dark or blurry areas in your central vision, and problems with color perception.

      There’s not yet a cure for AMD, but certain treatments can help prevent vision loss.

      Risk factors for developing AMD include:

      • Smoking
      • Obesity
      • Aging
      • Long-term sun exposure
      • Hypertension
      • Heart disease
      • Family history of AMD
      • Light-colored eyes
      • Farsightedness

      Diabetic Retinopathy (DR)

      Diabetic retinopathy is a complication of Type 1 or Type 2 diabetes that affects the light-sensitive tissue at the back of the eye called the retina.

      Initially, diabetic retinopathy shows no symptoms but can eventually lead to blindness. As it develops, it can cause increased floaters, impaired color vision, dark spots in your visual field, and blurred vision.

      Risk factors for developing diabetic retinopathy include:

      • Length of time from diabetes diagnosis — the longer you’ve had it, the higher your chances of developing visual complications
      • Uncontrolled blood sugar
      • Obesity
      • High cholesterol or blood pressure
      • Pregnancy
      • Smoking
      • African American, Hispanic, and Native American ethnicities
      • Family history of DR

      So, what’s the bottom line ?

      Multiple factors contribute to eye disease and vision loss, and some may even be relevant to you. If you think you may be at risk for vision loss or experience any of the symptoms listed above, speak with your eye doctor in Toronto as soon as possible. We also recommend you have your eyes thoroughly examined every 1-2 years, or as often as your eye doctor recommends. To schedule your comprehensive eye exam, call Corktown Eyecare today.

       

      Frequently Asked Questions With Our Toronto Eye Doctors

      1. Can blindness be prevented?

      When caught early, many eye diseases can be treated to halt or slow the progression of the disease and potentially prevent vision loss. The best things you can do to preserve your vision for the long term is to lead a healthy lifestyle and make sure you undergo a comprehensive eye exam every 1-2 years.

      1. Which eye diseases are genetically inherited?

      More than 350 ocular diseases have some sort of genetic component. Certain diseases, like retinitis pigmentosa and albinism, are directly inherited through chromosomal information. In other cases, a predisposition to the disease is inherited, rather than the disease itself.

      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.

At Corktown Eyecare in Toronto 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. Sanjay Vakani

      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.

      3 Benefits of Anti-Glare Coating

      Glare refers to the excessive brightness caused by direct or reflected light. It can cause eye strain, digital eye strain (when using a computer, for example), halos, and headaches. Glare can also reduce visibility, making it unsafe to drive.

      Anti-glare coating, also known as anti-reflective (AR) coating, is a thin layer applied to the surface of your eyeglass lenses that allows more light to pass through your lenses. By reducing the amount of glare that reflects off of your lenses, you can see more clearly and experience more comfortable vision. You can request anti-glare coating for lenses when you buy eyeglasses.

      AR Coating Offers 3 Major Advantages

      Better Appearance

      Without an anti-glare coating on your glasses, camera flashes and bright lights can reflect off your lenses. This can hinder your appearance when speaking to people or in meetings, cause flash reflections when picture-taking, and make it difficult to find the right angle for video calls. Anti-reflective coating eliminates the harsh reflections and allows others to clearly see your eyes and face.

      Reduced Digital Eye Strain

      You know that tired, irritated feeling you get after staring at a digital screen for several hours? That’s digital eye strain. Anti-glare coating helps reduce digital eye strain by lowering exposure to excessive glare from digital devices and lighting.

      Safe Driving at Night

      The bright headlights from cars driving in the opposite direction can pose a serious danger when driving at night. These sudden glares can lead you to momentarily lose focus of the view ahead. AR coating on your prescription eyewear effectively reduces reflections from headlights at night, allowing you to enjoy a better view of the road and safer driving at night.

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

      • A: Yes. 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.

      What You Should Know About Night Blindness

      If you don’t see well while driving at night, there’s a chance you have night blindness. Night blindness, or nyctalopia, is the inability to see well at night or in dim lighting. It’s not considered an eye disease, but rather a symptom of an underlying problem.

      Our eye doctor in Toronto can help diagnose, manage and treat your night blindness with specialized digital eye exams, so that you can enjoy being out and about at night again.

      Here are 4 things you should know about night blindness:

      Causes of Night Blindness

      The inability to see well at night can be the result of a condition such as:

      • Vitamin A Deficiency — Vitamin A helps keep your cornea, the layer at the front of your eye, clear; it’s also an important component of rhodopsin, a protein that enables you to see in low light conditions. Although uncommon in North America, deficiency of this vitamin can induce night blindness.
      • CataractsA buildup of protein clouds the eye’s lens, leading to impaired vision, especially at night and in poor lighting conditions.
      • Diabetic RetinopathyDamage to the eyes’ blood vessels and nerves can result in vision loss, including difficulty seeing at night.
      • GlaucomaThis group of eye diseases is associated with pressure build-up in the eye that damages the optic nerve. Both glaucoma and the medications used to treat it can cause night blindness.
      • MyopiaAlso called nearsightedness, myopia makes distant objects appear blurry, and patients with it describe a starburst effect around lights at night.
      • KeratoconusAn irregularly shaped cornea causes blurred vision and may involve sensitivity to light and glare which tend to be worse at night.
      • Retinitis Pigmentosa (RP)A progressive genetic eye disease which can be associated with other diseases, RP leads to night blindness and peripheral vision loss.
      • Usher SyndromeThis genetic condition causes both hearing loss and vision loss, including night blindness and RP, mentioned above.

      Symptoms of Nyctalopia

      Since night blindness is a symptom of some serious vision problems, it’s important to get your eyes checked regularly to ensure that everything is in good working order. Contact your eye doctor as soon as possible if you notice that you don’t see as well in dim light as you used to, such as when driving at night or when adjusting from being outdoors in the sunshine to being indoors.

      Symptoms of Night Blindness Include:

      • Reduced contrast sensitivity
      • Difficulty seeing people outdoors at night
      • Difficulty seeing in places with dim lighting, like a movie theater
      • Trouble adapting to the dark while driving
      • Excessive squinting at night
      • Trouble adjusting from bright areas to darker ones

      Treatments for Night Blindness

      Your eye doctor will want to diagnose the cause of your night blindness in order to treat it. For example, in the rare case of vitamin A deficiency, it can be treated with vitamin supplements and vitamin-A rich foods; myopia can be corrected with eyeglasses or contact lenses. Other conditions may require medications or surgery.

      If night blindness is caused by a birth defect, Usher syndrome, or retinitis pigmentosa, low vision aids and devices can help you make the most of your remaining vision.

      Prevention

      While there is no proven way to prevent night blindness resulting from genetic conditions or birth defects, consuming healthy, nourishing foods and taking certain vitamin supplements may prevent or slow the onset of some eye conditions that cause night blindness.

      If you experience poor vision at night or in dim lighting, we can help. Contact Corktown Eyecare in Toronto to schedule your appointment today.
