Many people tend to expect their eyesight to decline with age – perhaps requiring a stronger eyeglass prescription or “readers” to scan the daily paper. And while some changes to vision are linked to age, there are some steps we can all consider to help our eyes stay as healthy as possible.
Dr. Linda Chous, OD, chief eye care officer, UnitedHealthcare, is here to answer questions.
Are my eyes going to keep getting worse as I age? Is there anything I can do to slow the progression of vision decline?
By no means is your eyesight guaranteed to deteriorate with age, but it is perfectly normal to notice changes to your vision as the years pass. Unfortunately, there is nothing that can be done to stop normal vision changes. However, it is important to maintain regular appointments with your eye doctor (see below) to help identify pressing concerns.
With age, it is normal to experience:
• Minor adjustments to your eyeglasses prescription or needing to use “readers” for the first time;
• Trouble distinguishing colors, such as blue from black; and
• The need for more light to see well.
Although these changes are often normal, they can also be signs of conditions like cataracts or even diabetes. If you experience sudden vision loss or any rapid change to your eyesight, contact your eye care provider immediately.
I have noticed tiny spots or specks float across my vision. What is that all about?
Many people notice tiny specks within their field of vision. These small spots are tiny threads of protein that float across the gel-like substance between your eye’s lens and retina.
Usually there is no need to worry if you only notice these spots occasionally and they disappear after a few minutes, but only a dilated eye examination can determine the cause of the “floaters”.
However, if your vision is overcome by these specks or you are noticing vision loss, contact your eye doctor as soon as possible, as it could be a symptom of a sight-threating condition.
What are some of the most common vision-related diseases that come with age?
Here is the scoop on some of the most common age-related vision conditions:
Age-related macular degeneration (AMD)
AMD is the leading cause of vision loss in people over the age of 65. AMD causes damage to the macula, the small spot on the retina that enables people to see clearly and to view things straight ahead of them.
Common symptoms of AMD are distortion and blurring of the center of your field of vision. If caught in the early stage, there are potential benefits from taking certain prescription medications and nutritional supplements. However, late-stage AMD is much more difficult to treat.
Research has found that certain factors like heredity, ultraviolet light exposure, and smoking may increase the risk of developing AMD. Consult with your eye doctor to determine if a preventive treatment plan is right for you.
Cataracts
The lens in your eye is like a camera lens – it is clear and allows light to pass through to create an image. A cataract is the clouding of this lens, blocking the flow of light to the back of your eye (retina), which ultimately causes loss of sight.
There are many kinds of cataracts, and most usually form slowly and do not cause pain. If the clouding is small, it is possible you may not even notice it.
However, significant clouding can form in some people and, ultimately, negatively impact vision.
The good news is cataracts are treatable via surgery that removes the clouded lens and replaces it with a clear plastic lens. Cataract surgery is generally safe and is one of the most common surgeries done in the United States. Once a cataract is removed, it cannot grow back
Glaucoma
Glaucoma is caused by increased pressure inside the eye, which can cause permanent vision loss and blindness if left untreated. There are several types of glaucoma, but the most common form usually has no noticeable symptoms in the early stages – the only way to detect it is by visiting your eye care provider for routine testing.
Treatment may include prescription eye drops, oral medications, laser treatment surgery or a combination of any of these. It is important to find glaucoma early because once vision is lost, it cannot be regained.
