Glaucoma

What’s the Link Between Sleep and Glaucoma?

Sleep is usually a time for restoration and healing, but the way we sleep, how much we sleep and conditions like apnea can increase your chances of developing a serious eye condition: glaucoma.

Glaucoma is a sight-threatening optic nerve disease that generally affects people over 50 and, in its early stages, usually presents no symptoms until permanent vision loss has occurred.

This is why it’s essential to have your annual eye exam, especially if you’re 50 or older or at high risk of developing glaucoma. Regular check-ups enable your eye doctor to detect any eye problems, including glaucoma, early on. This can maximize the effectiveness of eye disease treatment and management.

If you’re due for your annual eye evaluation, schedule your eye exam with at in today.

Sleep and Risk Factors for Glaucoma

The quality and amount of our sleep and the way we sleep can increase our risk of developing glaucoma due to the following factors:

Eye Pressure and Glaucoma

The pressure within our eyes is affected by the amount of aqueous fluid and its ability to drain from the eyes. The aqueous fluid doesn’t drain efficiently when we lie flat on our back. The lack of drainage due to positioning during sleep can increase ocular pressure, which can strain the optic nerve and increase the risk of glaucoma.

Blood Pressure and Glaucoma

When we sleep, our blood pressure decreases. This is often good for people who suffer from hypertension because it takes some pressure off the cardiovascular system. However, long periods of low blood pressure, or hypotension, during sleep has been shown to exacerbate glaucoma symptoms.

Sleep Apnea and Glaucoma

Sleep apnea is marked by the occasional or frequent cessation of breathing during sleep. Usually, the person is unaware that they have sleep apnea, and only a partner or someone else who sleeps in the same room will notice that they make choking or gasping sounds as they stop breathing.

These periods of interrupted breathing can lessen the flow of oxygen and damage the optic nerve. There is an observable link between people who have sleep apnea and those who suffer from glaucoma, which may suggest a causal connection. The risk of people with sleep apnea developing glaucoma could be as high as 10 times the average. Individuals with sleep apnea should consult with their primary care physician, who can suggest lifestyle changes and devices such as oral appliances to help treat the condition.

Glaucoma and the Amount of Sleep

Too little or too much sleep can affect general health and contribute to eye problems. As mentioned above, extended periods of lying down can increase pressure on the optic nerve and contribute to the development of glaucoma. Yet too little sleep causes fatigue and has been associated with field vision loss.

According to a National Health and Nutrition Examination Survey (2005-2008), those who slept 10 hours or more a night had triple the risk of developing glaucoma compared to people who slept only 7 hours a night. Getting three hours of sleep a night tripled the risk of field vision loss.

Among other lifestyle glaucoma prevention tips, such as maintaining a healthy weight and not smoking, getting the right amount of sleep — not too much or too little — are important steps towards preventing optic nerve problems.

How Glaucoma Interferes with Sleep

Not only does the amount and way we sleep affect the development and progression of glaucoma. This optic nerve disease can interfere with our sleep. This occurs because the communication between the retina’s photosensitive cells and the hypothalamus — the part of the brain that contains the circadian clock that regulates sleep — is disrupted in glaucoma patients.

The hypothalamus no longer sends a message to the pineal gland to secrete melatonin and induce sleep at the proper time. The result: people with glaucoma may also experience sleep disturbances.

Risk factors for Glaucoma

Since many glaucoma patients do not experience symptoms prior to diagnosis, it is essential to undergo regular eye exams, especially for those considered at higher risk:

  • Aged 50 or older
  • Have a family history of glaucoma
  • Hypertension, diabetes, sickle cell anemia, heart disease
  • Are African American, Asian or Hispanic
  • Have corneas that thin at the center
  • Eye injury or prior eye surgery
  • High myopia (severe nearsightedness)
  • Take corticosteroids such as eye drops, pills or creams

How is Glaucoma Detected?

A digital eye exam maps out the eye with 3D full color images allowing your eye doctor to detect any problems early.

Retinal imaging can detect glaucoma and show optic nerve damage. Eye dilation is occasionally required before the imaging of the eye to enable your optometrist to more easily see the inside of your eye.

Q&A

What are the symptoms of glaucoma?

Symptoms vary depending on the type of glaucoma.

Open-angle glaucoma results from a lack of drainage of fluid from the eye. It generally has no obvious symptoms in its early phases. In its later stages, it presents with:

  • Blind spots and patches in the central or peripheral vision
  • Tunnel vision

Acute angle-closure glaucoma occurs when there is a sudden buildup of fluid pressure in the aqueous humor. Symptoms include:

  • Headaches
  • Pain in the eyes
  • Blurry vision
  • Nausea
  • Eye redness
  • Appearance of halos

What Causes a Feeling of Pressure Behind the Eye?

Glaucoma is often caused by pressure on the optic nerve. However, a feeling of pressure behind the eye is generally only felt with closed-angle glaucoma.

An excessive amount of fluid in the eye, called the aqueous humor or a sudden blockage to proper drainage causes a buildup and increased pressure on the optic nerve. Drainage of the aqueous humor is through the trabecular meshwork, which is located where the cornea and the iris meet.

Eye Vitamins: Can They Prevent or Treat Glaucoma?

Some initial studies have shown a potential link between Vitamin A and Vitamin C and a protective effect related to glaucoma. However, a systematic review of the literature on vitamins and glaucoma (Nutrients, March 2018), concludes that these studies are inconclusive and more research, including randomized clinical trials, are needed to establish any clear link between specific vitamins and preventing or treating glaucoma.

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 Ft. Lauderdale Eye Associates in Fort Lauderdale 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.

Why Does Bono Always Wear His Signature Shades?

Ever wonder why Bono always wears shades, even indoors? U2’s frontman doesn’t sport sunglasses simply as part of his image. Bono has had glaucoma—a build-up of pressure in the eyeball, which can damage the optic nerve and potentially lead to blindness if untreated—for over two decades now. 

The real reason he wears his trademark shades is due to this progressive, sight-robbing eye disease, to protect his sensitive eyes from light and glare. 

How Do Sunglasses Help People With Glaucoma?

People with glaucoma experience sensitivity to light (or photophobia) and glare, among other symptoms. When the sun is strong, those with this condition will be more affected by glare emanating from a variety of surfaces, like water, snow, sand or pavement, than the average person. Furthermore, certain glaucoma medications constrict the pupils, which can further contribute to acute sensitivity to glare and light, as well as redness and irritation.

That’s why people with glaucoma — and lots of people without glaucoma — feel best wearing sunglasses when outdoors on a sunny day, in a bright indoor space, or while driving in the early evening. 

Here’s How You Can Protect Your Eyes 

By wearing sunglasses that offer 100% UV protection, you can reduce your risk of developing sight robbing diseases, like cataracts and macular degeneration, and reduce glaucoma symptoms. Polarized lenses, in particular, can help with glare. With yearly comprehensive eye exams, early diagnosis and consistent treatment, you can prevent vision deterioration from glaucoma or similar sight-threatening eye diseases. Contact Ft. Lauderdale Eye Associates in Fort Lauderdale to book your eye doctor’s appointment today.

Q&A

Can glaucoma be cured?

While there is currently no cure for glaucoma, there are many effective treatment options available. Treatments that can help stop or slow the progression of glaucoma include eye drops, oral medications, as well as laser and surgical procedures. 

How can glaucoma vision loss be prevented?

The best way to avoid glaucoma-related eyesight deterioration is to undergo regular eye exams, as glaucoma can be detected and treated even in its early stages, which can prevent significant vision loss or blindness. That’s why routine eye exams that include glaucoma testing are so important.

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 Ft. Lauderdale Eye Associates in Fort Lauderdale 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. George A. Fournier

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 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 Fort Lauderdale 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 Ft. Lauderdale Eye Associates in Fort Lauderdale to schedule your appointment today.

Frequently Asked Questions with Dr. George A. Fournier MD

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.

6 Common Myths About Glaucoma

Glaucoma is an eye disease in which increased pressure causes progressive, permanent vision loss and even blindness. Unfortunately, many misconceptions about the disease can leave you misinformed. Below we sort fact from fiction by debunking 6 of the most common glaucoma myths.

Glaucoma Facts vs. Myths

MYTH 1: Glaucoma is a single disease

FACT

Glaucoma is a group of eye diseases; the most common ones are open-angle glaucoma (OAG) and angle-closure glaucoma (ACG).

In open-angle glaucoma, the drainage structure in your eye (called the trabecular meshwork) doesn’t allow the fluid inside the eye to flow out as it should, causing an increase in internal ocular pressure that damages the optic nerve. OAG develops slowly, and usually by the time people perceive symptoms, such as peripheral vision loss, they already have optic nerve damage.

In angle-closure glaucoma, the eye doesn’t drain fluid as it should because the drainage channel between your iris and cornea becomes too narrow, causing increased eye pressure. This pressure damages the optic nerve, leading to vision loss. ACG can occur suddenly or gradually.

MYTH 2: Only the elderly suffer from glaucoma

FACT

Although it’s true that people over 60 are at a greater risk of developing open-angle glaucoma compared to people in their 40s, there are other types of glaucoma that can affect people aged 20 to 50 and even young infants (due to abnormal ocular development).

In addition to age, those with a higher risk of developing glaucoma include:

  • African Americans and Hispanics
  • Individuals with a family history of glaucoma
  • Patients with cardiovascular disease, diabetes, or sickle cell anemia
  • Those who have previously sustained an eye injury
  • People taking steroid medications over the long term

MYTH 3: Glaucoma shows symptoms early on

FACT

The most common form of glaucoma, open-angle glaucoma, shows virtually no signs or symptoms until its later stages when vision loss sets in. Despite what people may think, the increased eye pressure causes no pain. And since peripheral vision is the first to go, you may not recognize vision loss until your vision has become significantly impaired. The only way to detect glaucoma is to undergo a comprehensive eye exam.

MYTH 4: Nothing can be done once you have glaucoma

FACT

While there’s currently no cure for glaucoma, many effective treatment options exist: eye drops, oral medications, as well as laser and surgical procedures that can help slow glaucoma progression. Each treatment option is used to get the fluid to flow properly out of the eye, reducing pressure inside the eye and decreasing damage to the optic nerve.

MYTH 5: Testing for glaucoma is painful

FACT

Actually, testing for glaucoma is practically painless. One of the tests includes a non-contact device that blows a gentle puff of air into each eye to test the intraocular pressure. The sound of the puff may be startling, but it’s over in a second and is painless. With the Goldmann applanation tonometry test, an anesthetic eye drop is inserted into each eye, which may cause a stinging sensation for a few seconds. Your eye doctor will then use a blue light to quickly and gently touch the cornea to precisely measure intraocular pressure. The most accurate of all, however, are visual field testing and OCT (optical coherence tomography), non-invasive imaging, both of which are also painless.

MYTH 6: You can’t prevent glaucoma

FACT

Regular eye exams are the only way to prevent glaucoma, as blindness or significant vision loss can be prevented if the disease is diagnosed and treated in the early stages. That’s why routine comprehensive eye exams which include glaucoma testing are so important.

Getting your eyes checked regularly can ensure that any existing eye problems are detected early enough to prevent or slow ocular damage. Contact Ft. Lauderdale Eye Associates in Fort Lauderdale to book your comprehensive eye exam today!

Frequently Asked Questions with Dr. George A. Fournier MD

Q: If one of my parents has glaucoma, does that mean I will develop it as well at some point?

  • A: Having a parent with glaucoma does not mean that the child will automatically develop the condition too. However, those people with an immediate family history (parents, siblings) of glaucoma are at more risk to develop this disease. Patients should have a comprehensive eye examination each year to evaluate the health of the eyes and to look for signs of glaucoma. Some of these signs can be an increase in the pressure of the eyes as well as changes to the appearance of the optic nerve. Many times there are no symptoms noticed by the patient. If there is suspicion of glaucoma, more frequent visits to the eye doctor along with additional nerve testing are often required.

Q: Why do I need to scan my retinas/back of the eye?

  • A: The retina shows us a lot about the overall ocular health as well as systemic conditions that can affect the eyes. Often diabetes, hypertension or high cholesterol can be observed from a retinal scan. Also, retinal scans allow us to diagnose and treat macular degeneration and glaucoma. Scans are often very important for a complete eye check up.

Does Obesity Impact Eye Health?

Nation-wide awareness about the vast dangers of obesity is at an all-time high, with TV shows like “The Biggest Loser” and health initiatives such as Michelle Obama’s “Let’s Move!” campaign shining a spotlight on the importance of fitness and good nutrition. However, despite the public’s knowledge of obesity’s effects on hypertension, stroke, and diabetes, many are not aware of how it damages eye health and vision.

Increasing evidence shows that people who are clinically obese have an elevated risk of developing serious eye diseases. It is widely known that expanding waistlines place people at a higher risk of getting diabetes, heart disease, and cancer — but researchers say the link between obesity and deteriorating vision is the “risk factor that no one talks about”. Professor Michael Belkin and Dr. Zohar Habot-Wilner, from the Goldschleger Eye Institute at the Sheba Medical Center, found a consistently strong correlation between obesity and the development of four major eye diseases that may cause blindness:

  • Age-related macular degeneration (AMD)
  • Cataracts
  • Glaucoma
  • Diabetic retinopathy

The researchers said that although the evidence was out there suggesting a link between obesity and these conditions, their study emphasizes the optometric risks of obesity which can help motivate people to shed those extra pounds.

How Obesity Contributes to Eye Disease

A Body Mass Index (BMI) of 25 is considered overweight and above 30 is regarded as obese. A high BMI is tied to several chronic systemic health conditions such as diabetes, cardiovascular disease, and stroke, among others. Recent research indicates that a handful of ocular diseases can now be added to that list.

Serious eye conditions such as diabetic retinopathy, glaucoma, and age-related macular degeneration are more common in individuals with obesity, as well as floppy eyelid syndrome, retinal vein occlusions, thyroid-related eye diseases, and stroke-related vision loss.

The connection between obesity and these eye diseases is likely due to the increased risk of peripheral artery disease. This occurs when the tiny blood vessels bringing oxygen to parts of your body like the feet, kidneys, and eyes become compromised.

Your eyes are particularly prone to damage from obesity because the blood vessels in the eyes (called arterioles) are easily blocked, since they’re extremely thin and small — as thin as ½ the width of a human hair!

Most people are not aware that obesity may increase the rate of developing cataracts, too. Cataracts result when the focusing lens in the eye becomes cloudy and requires surgery to be replaced. In addition to age, cataract development is associated with obesity, poor nutrition, gout, diabetes and high blood sugar levels, though the exact cause isn’t clear.

A Healthy Lifestyle Can Reduce Your Risk of Ocular Disease

Knowing about the risk of vision loss may give those with a high BMI the extra motivational boost they need to lose weight. The good news is that a few lifestyle changes can reduce the associated risks.

An active lifestyle and a balanced, nutritious diet lower obesity and improve overall physical and eye health. Give your body a boost by incorporating important nutrients, such as vitamins C and E, zeaxanthin, omega 3, zinc, and lutein, many of which are found in green leafy and dark orange vegetables, as they have been shown to reduce the onset, progression, and severity of certain eye diseases.

We Can Help Keep Your Eyes Healthy in Fort Lauderdale

While a healthy diet and regular exercise greatly increase your chances of living a disease-free long life, they alone are not enough to ensure long term healthy eyesight. Regular eye exams with Dr. George A. Fournier can help prevent or detect the onset of ocular disease, and maintain vision that is clear and comfortable.
