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 Eyeworks in Ft. Worth 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 Drinking Wine May Help Prevent Cataracts

Some say that just like fine wine, people get better with age. While this may be true for character and personality, it often isn’t the case as it comes to one’s eyes. Age is often accompanied with all sorts of eye problems, like macular degeneration, dry eyes and cataracts.

But these eye conditions aren’t inevitable. Certain actions, habits, foods (and drinks!) may help ward off or reduce the severity of age-related eye problems—like cataracts.

But First, What Are Cataracts?

Cataracts are a clouding of the eye’s lens that affects millions of people in North America.

Symptoms of cataracts include:

  • Cloudy or blurred vision
  • Colors that seem faded
  • Trouble seeing at night
  • Double vision
  • Seeing halos around lights
  • The need to frequently update one’s corrective lens prescription

Cataracts occur naturally with age and may not always require treatment if a person’s vision remains mostly clear. Keep in mind that eye injury and certain eye diseases may also lead to cataracts.

The main treatment for cataracts is cataract surgery—it replaces the natural, cloudy lens with a clear, artificial lens.

The onset of cataracts may be prevented or at least delayed by wearing sunglasses, quitting smoking, having regular eye exams and eating nutritious foods (yes, wine included).

How Drinking Wine May Help Prevent Cataract

Wine is loaded with eye-healthy antioxidants that may protect the eyes against cataracts and other age-related conditions. Several studies have reported numerous benefits of regular and moderate wine consumption, including protection against heart disease and macular degeneration.

A recent study, published in the journal Ophthalmology, on the relationship between wine and cataracts involves data from 490,000 individuals who voluntarily disclosed details about their lifestyle and eating habits. When all other factors were considered (age, gender, smoking, weight, diabetes, ethnicity), the findings concluded that consuming about 6.5 glasses of wine per week may decrease a person’s risk of needing cataract surgery.

According to the study, wine drinkers seem to be the least likely candidates for cataract surgery when compared to non-drinkers or those who consumed other varieties of alcohol, like beer and liquor.

It’s important to note that the study does not establish a causal relationship between wine consumption and cataract surgery—only a significant association linking the two.

The head of the study, Dr. Sharon Chua, further explains that the development of cataracts may be due to gradual oxidative stress, which is a natural part of aging. The abundance of polyphenol antioxidants in wine may help counteract oxidative stress.

Here’s the breakdown:

  • Participants who consumed a glass of wine 1-2 times per week had a 7% reduced need for cataract surgery than those who drank 1-3 times or less per month.
  • Participants who drank a glass of wine daily or almost daily experienced a 5-6% increased risk of cataract surgery compared to those who drank 1-4 times a week.
  • Consuming red wine weekly provided participants with a 14% reduced need for cataract surgery compared to those who abstained.
  • Weekly consumption of white wine and champagne reduced the need for cataract surgery by 10%.

So, what’s the bottom line?

Antioxidants are super beneficial for eye health and may help reduce your risk of developing a severe case of cataracts that would require surgery. This study suggests that moderate wine consumption on a weekly basis may lower your risk of cataract surgery when coupled with an antioxidant-rich diet. Furthermore, red wine seemed to have the most dramatic effect compared to white wine or other forms of alcohol.

Speak to your healthcare provider before making any changes to your diet, just to be safe.

What Causes Halos Around Lights?

EYEWORKS Local Cataract, Astigmatism, Fuch’s Dystrophy and Glaucoma Eye exams and treatment near you in Fort Worth, Texas

Have you ever seen bright rings or “halos” around sources of light? Read on to learn what can cause halos and when they’re a reason to visit an eye doctor near you.

For local Management of Ocular Diseases near you in Fort Worth, Texas

Seeing bright rings or “halos” around sources of light can either be normal or a cause for concern. Below, we’ll explain the most common reasons that people see halos and when you should visit your eye doctor.

We see halos around light fixtures and headlights when light entering the eye from a bright object is bent in an unusual way. This causes the bright light to appear as if it is surrounded by a ring of light, known as a halo. Several conditions can cause light to bend in this way.

  • CataractsA cataract is a clouding of the eye’s natural lens. Cataracts usually develop slowly and are most often seen in older people.

    When the lens becomes cloudy, light is dispersed abnormally as it enters the eye and causes a person to see halos around lights. In fact, seeing halos around lights is one of the most common symptoms of cataracts. Other symptoms that may accompany cataracts are blurred vision, light sensitivity, and difficulty seeing at night.

  • AstigmatismThis eye condition occurs when the cornea (the front surface of the eye) is irregularly curved. People with astigmatism may see halos around lights because of the way the cornea refracts incoming light.
  • Fuch’s Dystrophy This progressive genetic disease causes the cornea to swell. As the cornea swells and becomes misshapen, it causes light to enter at an incorrect angle. As a result, people with this condition see halos around lights.
  • GlaucomaGlaucoma occurs when the optic nerve becomes damaged due to high inner eye pressure, and is a leading cause of blindness worldwide. Seeing halos around lights can be an early sign of acute glaucoma, which is considered a medical emergency.

    If you suddenly start seeing halos around lights in addition to other symptoms like headache, vomiting, blurred vision, eye pain, and weakness, seek medical care without delay.

  • Dry Eye SyndromeDry eye syndrome occurs when the eyes are chronically dry. In moderate to severe cases, the eye’s surface can become irregularly shaped, which can cause light to enter at an odd angle.

When To Visit Your Eye Doctor

If you see halos around lights, it’s best to schedule a timely eye exam at an eye clinic near you, even if you suspect you know why it’s happening.

A comprehensive eye exam by a qualified eye care professional is the only way to rule out a serious problem.

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, 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 Fort Worth eye doctor is always ready to answer your questions about eye disease and Contact lenses.

  • What is a cataract? How will I know when I have one? What can be done to fix it?

    A cataract is a clouding of the crystalline lens. The crystalline lens sits behind the iris or the colored part of the eye. Its function is to fine-tune our focusing system by changing shape as we view objects at different distances. Our lens eventually loses its ability to change shape; this is when we require reading glasses or bifocals. In addition, the crystalline lens can become cloudy or yellow as a part of normal aging. This is also known as an age-related cataract. Normal, age-related cataracts are unavoidable and everyone will develop them at some point if they live long enough. The discoloration of the lens leads to an overall blur, a decrease in contrast sensitivity, and a worsening of glare, especially at nighttime. Because they tend to develop gradually, the symptoms are often unnoticed by the patient. A yearly eye exam will allow your optometrist the opportunity to identify cataracts and advise on how to proceed. When your optometrist decides your cataracts are affecting your vision and are advanced enough to remove, you will meet with an ophthalmologist. Cataract surgery is a safe and effective outpatient procedure that will reverse any vision loss caused by cataracts, and it is usually covered by your medical insurance.

  • My previous eye doctor told me I have “stigma!” Am I going to go blind?

    Stigma is actually referring to a type of refractive error known properly as astigmatism, and no, you will not go blind from having astigmatism; it is not a disease, in fact, it is relatively common. There are three types of refractive error, myopia, hyperopia, and astigmatism. The former two are more regularly referred to as nearsighted (cannot see far away) and farsighted (cannot see up close). Astigmatism is simply the third category; it affects both the near and far vision at the same time. Much like nearsightedness or farsightedness, astigmatism is corrected using glasses or contacts. Technically speaking an eye with astigmatism requires two different prescriptions to correct vision in one eye due to the more oval shape of the cornea. This will require a more specialized contact lens and a more in-depth fitting procedure. Nonetheless, your eye care provider can, and will, correct your astigmatism with glasses and/or contacts.

  • What exactly is glaucoma?

    Glaucoma is a condition in which the eye’s intraocular pressure (IOP) is too high. This means that your eye has too much aqueous humor in it, either because it produced too much, or because it’s not draining properly. Other symptoms are optic nerve damage and vision loss. Glaucoma is a silent disease that robs the patient of their peripheral vision. Early detection is very important.

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

5 Common Myths About Cataracts

5 Common Myths About Cataracts 640Most people have heard of cataracts, or know someone who has undergone cataract surgery. But despite it being a well-known eye condition, there’s still a lot of confusion around cataracts.

Below, we’ll clear up some common misconceptions and set the record straight.

Myth #1: Cataracts are Growths Within the Eye

FACT: Cataracts aren’t growths—rather, they’re changes in the eye’s natural lens. Cataracts occur when the protein cells in the lens start to deteriorate and clump together, resulting in cloudiness. A person with cataracts will typically have cloudy vision accompanied with a yellow or brown tint.

Myth #2: Only Older People Get Cataracts

FACT: People of all ages—even newborns—can have cataracts. While it’s accurate to say because cataracts are a natural process of aging, and affects the elderly more often than the young, certain medications and eye trauma can also lead to cataracts.

Myth#3: Lifestyle Changes Can Treat or Reverse Cataracts

FACT: Once you have a cataract, the only way to cure it is with surgery in order to remove the cataract and implant a new clear lens. Healthy lifestyle choices like eating well, getting regular exercise, and sleeping enough can all impact eye health and overall health, but they cannot reverse cataracts.

Myth #4: You Can’t Do Anything to Prevent Cataracts

FACT: While there is no surefire way of preventing cataracts, wearing 100% UV blocking sunglasses outdoors and incorporating eye-healthy foods into your diet, like leafy greens and colorful vegetables, may delay their onset.

Myth#5: If You Have Cataracts, You Definitely Need Cataract Surgery

FACT: You only need to have your cataracts surgically removed if they interfere with your vision and impact your lifestyle. If you’re able to safely perform activities, such as driving at night, you don’t necessarily need surgery right away. However, be sure that your eye doctor monitors you for cataract-related vision loss.

At EYEWORKS Ophthalmology Center, we help patients navigate a wide range of eye health matters, and can help you decide whether to undergo cataract surgery or other treatments. To schedule your consultation, call EYEWORKS Ophthalmology Center today.

EYEWORKS Ophthalmology Center serves patients from Ft. Worth, Southlake, River Oaks, Benbrook, and throughout Texas.

Frequently Asked Questions with Dr. Richard Chu

 

Q: Can cataracts return after surgery?

  • A: No. During surgery, the natural lens is removed and replaced with an artificial one that will remain clear. If the membrane that holds the artificial lens starts to deteriorate, your vision may turn cloudy again — but this is easily treatable with a quick laser procedure to restore sharp vision.

Q: What other symptoms are associated with cataracts, aside from cloudy vision?

  • A: Cataracts are usually a painless condition, but you may experience the following symptoms associated with your cataracts: double vision, seeing halos around lights, perceiving colors as faded or yellowed, and changes in your lens prescription.

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 Ft. Worth 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 Eyeworks in Ft. Worth to schedule your appointment today.

Frequently Asked Questions with Dr. Richard Chu, D.O.

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.

Exercise Can Reduce the Risk of Cataracts

Grandad Granddaughter GlaucomaResearchers have discovered that people who engage in moderate exercise have a 10% lower chance of developing age-related cataracts than people who don’t exercise, according to the International Journal of Ophthalmology.

An estimated 24% of adults do little to no physical activity, which puts them at greater risk of cataracts and other age-related vision problems, not to mention heart disease, high blood pressure, and more.

Getting into a regular exercise routine will not only boost your fitness; it can also help protect your eyesight! It is important to make time in your life to exercise regularly, as it can reduce the risk of developing cataracts and keep you healthy overall.

What are Common Signs of Cataracts?

Cataracts are the leading cause of vision loss and blindness worldwide. Fortunately, they can be easily treated with surgery. If you begin to notice the following symptoms, contact your eye doctor immediately:

  • Cloudy spots or hazy vision
  • Difficulty seeing at night
  • Increased sensitivity to light
  • Light halos or glares, especially at night

With prevention and early detection, you can take greater control over your visual outcomes as you age.

How Does Exercise Benefit Our Eyes?

Exercise increases our antioxidant enzyme activity, which results in less breakdown and clouding of our natural lens. It is also known to reduce oxidative stress that can cause cell damage in the eye, which in turn causes cataracts.

Over time, exercise can also increase our HDL, the “good” cholesterol, which helps carry more antioxidants throughout the body, including our natural lens.

In addition to exercise, your diet also plays crucial role. An increased and consistent intake of vitamins A, E, and C has been shown to benefit eye health.

What Kind of Exercise Should I Do?

The risk of developing cataracts could potentially be reduced by 2% for every hour a person walks or cycles daily, the researchers concluded.

If you do not currently exercise, start off with a small amount and gradually increase your physical activity. You should aim to exercise several days a week for 30 minutes. This will improve your overall health and reduce the risk of cataracts.

Always consult your physician before starting an exercise regimen.

Running, walking, and biking are common activities found to help decrease the risk of cataracts.

8 Ways Your Eyes Change With Age

Our eyes and vision change with age. Your eye doctor can monitor these changes — some of which are a natural part of the aging process — and identify any eye conditions or diseases early enough to treat them and prevent vision loss. Read on to learn more about the different types of eye changes one may encounter with age.

Age-Related Eye Conditions and Diseases

Cataracts

If your vision is starting to get blurry, you may be developing cataracts. There are a few types of cataracts, but the one usually caused by aging is known as a “nuclear cataract”. At first, it may lead to increased nearsightedness or even a temporary improvement in your reading vision. But with time, the lens gradually turns more densely yellow and clouds your vision. As the cataract slowly progresses, the lens may even turn brown. Advanced yellowing or browning of the lens can lead to difficulty distinguishing between shades of color, and left untreated, it can eventually lead to blindness. Luckily, cataract surgery, where the cloudy lens is replaced with a clear lens, is an extremely safe and effective treatment option.

Blepharoptosis

Blepharoptosis or ptosis is a drooping of the upper eyelid that may affect one or both eyes. The eyelid may droop only slightly or may droop enough to cover the pupil and block vision. It occurs when there is a weakness of the eye’s levator muscle that lifts the eyelid. This condition is usually caused by aging, eye surgery, or disease affecting the muscle or its nerve. Fortunately, blepharoptosis can be corrected with surgery.

Vitreous detachment

This occurs when the gel-like vitreous fluid inside the eye begins to liquefy and pull away from the retina, causing “spots and floaters” and, sometimes, flashes of light. This occurrence is usually harmless, but floaters and flashes of light can also signal the beginning of a detached retina — a serious problem that can cause blindness, and requires immediate treatment. If you experience sudden or worsening flashes and increased floaters, see Dr. Richard Chu immediately to determine the cause.

Other Age-Related Changes

In addition to the above eye conditions and diseases, the structure of our eyes and vision change as we get older.

Presbyopia

Why do people in their 40s and 50s have more difficulty focusing on near objects like books and phone screens? The lens inside the eye begins to lose its ability to change shape and bring near objects into focus, a process is called presbyopia. Over time, presbyopia, also known as age-related farsightedness, will become more pronounced and you will eventually need reading glasses to see clearly. You may need multiple prescriptions – one prescription to enable you to see up close, one for intermediate distance, and one for distance vision. In that case, people often get bifocals, multifocals or PALs, and they can be combined with contact lenses as well.

Reduced pupil size

As we age, our reaction to light and the muscles that control our pupil size lose some strength. This causes the pupil to become smaller and less responsive to changes in ambient lighting. The result? It becomes harder to clearly see objects, such as a menu, in a low-light setting like a restaurant.

Dry eye

Our tear glands produce fewer tears and the tears they produce have less moisturizing oils. Your eye doctor can determine whether your dry eye is age-related or due to another condition, and will recommend the right over-the-counter or prescription eye drops, or other effective and lasting treatments, to alleviate the dryness and restore comfort.

Loss of peripheral vision

Aging causes a 1-3 degree loss of peripheral vision per decade of life. In fact, one may reach a peripheral visual field loss of 20-30 degrees by the time they reach their 70s and 80s. While peripheral vision loss is a normal part of aging, it can also indicate the presence of a serious eye disease, like glaucoma. The best way to ascertain the cause is by getting an eye exam.

Decreased color vision

The cells in the retina responsible for normal color vision tend to decline as we age, causing colors to become less bright and the contrast between different colors to be less noticeable. Though a normal part of aging, faded colors can at times signal a more serious ocular problem.

Beyond the normal changes that come with age, the risk of developing a serious eye disease, such as age related macular degeneration and glaucoma, increases. Routine eye exams are essential to keeping your eyes healthy. Your eye doctor can determine whether your symptoms are caused by an eye problem or are a normal byproduct of aging.

If you or a loved one suffers from impaired vision, we can help. To find out more and to schedule your annual eye doctor’s appointment, contact Eyeworks in Ft. Worth today.

What Causes Cataracts? What Are the Early Signs?

Academy of Ophthalmology has estimated that about half of all Americans have cataracts by 75 years old! At our eye care center in Ft. Worth, Southlake and , we diagnose cataracts regularly when performing eye exams for our older patients. A comprehensive eye exam is the only way to reliably diagnose cataracts.

Causes of Cataracts

The development of cataracts is actually seen as a regular, “normal” part of aging. As you get older, the crystalline lens of your eyes begins to harden and turn yellow. Over time, the cataracts will worsen. That’s why it’s vital to know the early signs so you can benefit from treatment as early as possible. Early treatment may be able to slow the progression of cataracts.

Early Signs of Cataracts

Cataracts differ in terms of their severity, so not everyone will experience the same signs and symptoms. These are the most common symptoms:

  • Blurry or cloudy vision, like you’re looking through a foggy window
  • Dim color perception, everything may appear with a yellow tinge or faded
  • Difficulty seeing at night
  • Increased light sensitivity, bright lights may cause you to squint or trigger headaches
  • Seeing halos and glare

Slowing the Progression of Cataracts

Often, small cataracts develop slowly, giving you plenty of time to consider options and discuss treatment with your eye doctor. While the progression can be slow, cataracts never simply disappear on their own, and eventually, they can cause blindness. Certain actions can help slow the development, such as:

  • Wearing sunglasses to protect your eyes from prolonged exposure to UV rays
  • Avoiding steroid eye drops
  • Eating a healthy diet

Cataract Surgery

Once the symptoms of cataracts deteriorate to the degree that they disrupt your everyday life, it’s time to discuss cataract removal surgery with our eye doctors in Ft. Worth, Southlake and Downtown. The success rate and recovery are excellent.

At Eyeworks, we put your family’s needs first. Talk to us about how we can help you maintain healthy vision. Call us today: 817-346-7077 or book an appointment online to see one of our Ft. Worth eye doctors.

Why You Regularly Need to Replace Your Sunglasses

Did you know that sunglasses, or at least sunglass lenses, regularly need to be replaced? 

According to a study conducted at the University of São Paulo, the UV protection that sunglasses provide deteriorates over time. You may adore your current ones, but if you’ve been rocking those shades for two or more years, it might be time to get a new pair. 

In addition to the UV-blocking properties, anti-reflective and anti-scratch coatings wear down, and the frame material may become brittle over the years, too. Even if you have the most durable sunglasses available, regular lens-replacement is the best way to ensure that your vision is maximally protected from the harmful effects of ultraviolet light. 

UV Light and Sunglasses

The protective efficacy of your sunglasses comes in large part from the lens coating of dyes and pigments that reflect and absorb ultraviolet radiation. They create a barrier that prevents UV radiation from penetrating your eyes.

However, this protective coating can, and often does, break down over time. Wear and tear can cause an invisible web of tiny abrasions, compromising its UV-blocking power. Furthermore, the protective dyes and pigments aren’t able to absorb UV rays indefinitely; the more sunlight they’re exposed to, the more rapidly they’ll become ineffective. 

A pair of shades worn on occasion and in mild conditions is likely to remain effective longer than a pair that is heavily used in a more intensely sunny environment. For example, if you spend long days on the water paddling, kayaking, or canoeing, the protective coating on your lenses will deteriorate more quickly than it would if you only wear your shades to go grocery shopping or sit in a cafe. 

Why It’s Important to Protect Your Eyes From UV

Protecting your eyes from the sun is critical no matter where in the world you are, as UV exposure places you at risk for developing eye diseases like eye cancer, pterygium, and pinguecula — which can result in disfigurement and discomfort — as well as cataracts and macular degeneration — which cause vision loss and, in severe cases, blindness.

Even short-term overexposure can result in photokeratitis, a corneal sunburn. Symptoms include eye pain, swelling, light sensitivity, and temporary vision loss. Some people experience it when spending too much time boating or skiing without wearing eye protection. Snow and water can increase solar exposure because they reflect sunlight toward your face.  

What to Look for When Getting New Sunglasses

When choosing new sunglasses, make sure they’re labeled 100% UV protection or UV400. Although most pairs sold in the United States and Canada offer this degree of protection, it’s still worth confirming before making the purchase. Keep in mind that factors like cost, polarization, lens color, or darkness don’t have much to do with the level of UV protection. Even clear prescription lenses can be UV protective. 

It’s important to note that there is a lot of counterfeit sunwear in the marketplace. This is dangerous since counterfeit eyewear may not provide much-needed ultraviolet protection. So if the price of a renowned brand is too good to be true, it’s probably a fake. 

The size and fit of the sunglasses is important. Bigger is definitely better if you spend a lot of time outdoors. Larger wrap-around eyewear is best if you regularly ski or spend many hours in the water, as this style blocks light from all directions. 

To find out whether it’s still safe to wear your favorite shades, visit a Ft. Worth eye doctor to determine whether your lenses still offer the right level of UV protection. It’s also a good opportunity to discuss prescription sunwear.

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.
