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 Dr. Terry Tsang Optometry, Inc. in Irvine 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. 

 

What’s The Link Between Obesity And Eye Disease?

People who are obese are at higher risk of developing some sight-threatening eye conditions and diseases. Read on to discover why, and how we can help.

It is well documented that obesity impacts health in numerous ways, from a higher incidence of diabetes to cardiovascular disease. What many people don’t know is obesity’s negative effect on vision and eye health. Speak with our Eye care professionals at Dr. Terry Tsang Optometry, Inc. about any concerns you may have about your eye health or vision.

There is increasing evidence that obese individuals have a greater risk of developing serious, sight-threatening eye diseases.

Researchers at the Goldschleger Eye Institute at the Sheba Medical Center found a consistent link between obesity and the development of age-related macular degeneration, cataracts, glaucoma, and diabetic retinopathy.

The researchers noted that the public is largely unaware of this link, despite the evidence. If more people knew about the risk, they said, it might motivate them to try to shed some extra weight.

How Does Obesity Impact The Eyes?

A body mass index (BMI) of 25-30 is considered overweight and any BMI over 30 is considered obese. Recent studies indicate that a handful of ocular diseases can now be added to the list of medical conditions associated with an elevated BMI.

Diabetic retinopathy, floppy eyelid syndrome, retinal vein occlusions, stroke-related vision loss, and age-related macular degeneration are all risk factors of obesity.

While the cause is not yet certain, researchers believe this may be due to the peripheral artery disease prevalent among people who are obese. When the tiny blood vessels around the eyes are compromised, they may have trouble delivering oxygen and other nutrients to the eye area.

Obesity is also a risk factor for developing cataracts (the clouding of the eye’s natural lens). Poor nutrition or high blood sugar levels, which are commonly found in people with obesity, may contribute to the cloudiness.

Although obesity may contribute to cataract formation, losing weight may not significantly reduce the risk of developing them, partly because cataracts are also a common consequence of aging, whatever one’s weight.

Additionally, morbid obesity is associated with higher inner eye pressure, which may increase one’s risk of glaucoma and glaucomatous optic neuropathy — leading causes of vision loss and blindness. Morbid obesity is defined as having a BMI of 40 or above, or 35 and above with health conditions like high blood pressure or diabetes.

Stay Active, Healthy, and Have Regular Eye Exams

An active lifestyle and a nutritious diet can help you maintain a healthy weight and improve overall physical and eye health. Try to include several key nutrients into your diets, such as vitamins C and E, zeaxanthin, omega-3, zinc, and lutein, as they may help delay or prevent certain eye diseases.

While a balanced diet and regular exercise significantly increase your chance of living a healthy life, it’s also crucial to have regular eye exams. A comprehensive eye exam with Dr. Terry Tsang can help detect the onset of ocular disease and ensure the earliest and most effective treatment to preserve your gift of sight.

  • Is it possible to prevent Macular Degeneration?

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

  • My doctor says I have a cataract, but he wants to wait a while before removing it. Why?

    A cataract usually starts very small and practically unnoticeable but grows gradually larger and cloudier. Your doctor is probably waiting until the cataract interferes significantly with your vision and your lifestyle. You need to continue to visit your eye doctor regularly so the cataract’s progress is monitored. Some cataracts never really reach the stage where they should be removed. If your cataract is interfering with your vision to the point where it is unsafe to drive, or doing everyday tasks is difficult, then it’s time to discuss surgery with your doctor.

  • 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.

  • What is diabetic retinopathy?

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

What 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 can help diagnose, manage and treat your night blindness so that you can enjoy being out 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. 

Cataracts — A buildup of protein clouds the eye’s lens, leading to impaired vision, especially at night and in poor lighting conditions.

Diabetic Retinopathy — Damage to the eyes’ blood vessels and nerves can result in vision loss, including difficulty seeing at night.  

Glaucoma — This 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. 

Myopia — Also called nearsightedness, myopia makes distant objects appear blurry, and patients with it describe a starburst effect around lights at night.

Keratoconus — An 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 Syndrome — This 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.
