Aging and Your EyesDid you know that many older people have good eyesight into their 80's and beyond? Growing older does not always mean you see poorly. But age brings changes that can weaken your eyes.
There are some easy things to try when these changes happen. You might add brighter lights in more places around the house--like at work counters, stairways, and favorite reading places. This may help you see better and can sometimes prevent accidents caused by weak eyesight.
While older people have more eye problems and eye diseases than younger people, you can prevent or correct many of them by:
- Seeing your doctor
regularly to check for diseases like diabetes, which could cause
eye problems if not treated.
- Having a complete eye
exam with an eye specialist every 1 to 2 years. Most eye diseases
can be treated when they are found early. The eye doctor should
enlarge (dilate) your pupils by putting drops in your eyes. This
is the only way to find some eye diseases that have no early signs
or symptoms. The eye doctor should test your eyesight, your
glasses, and your eye muscles. You should also have a test for
- Taking extra care if you have diabetes or a family history of eye disease. Have an eye exam through dilated pupils every year. See an eye doctor at once if you have any loss or dimness of eyesight, eye pain, fluids coming from the eye, double vision, redness, or swelling of your eye or eyelid.
Common Eye ComplaintsPresbyopia (prez-bee-OH-pee-uh) is a slow loss of ability to see close objects or small print. It is a normal process that happens over a lifetime. You may not notice any change until after the age of 40. People with presbyopia often hold reading materials at arm's length. Some get headaches or "tired eyes" while reading or doing other close work. Presbyopia is often corrected with reading glasses.
Floaters are tiny spots or specks that float across the field of vision. Most people notice them in well-lit rooms or outdoors on a bright day. Floaters often are normal, but sometimes they warn of eye problems such as retinal detachment, especially if they happen with light flashes. If you notice a sudden change in the type or number of spots or flashes, see your eye doctor.
Dry eyes happen when tear glands don't make enough tears or make poor quality tears. Dry tears can be uncomfortable, causing itching, burning, or even some loss of vision. Your eye doctor may suggest using a humidifier in the home or special eye drops ("artificial tears"). Surgery may be needed for more serious cases of dry eyes.
Tearing having too many tears can come from being sensitive to light, wind, or temperature changes. Protecting your eyes (by wearing sunglasses, for instance) sometimes solves the problem. Tearing may also mean that you have a more serious problem, such as an eye infection or a blocked tear duct. Your eye doctor can treat or correct both of these conditions.
Eye Diseases and Disorders Common in Older PeopleCataracts are cloudy areas in part or all of the eye lens. The lens is usually clear and lets light through. Cataracts keep light from easily passing through the lens, and this causes loss of eyesight. Cataracts often form slowly and cause no pain, redness, or tearing in the eye. Some stay small and don't change eyesight very much. If a cataract becomes large or thick, it usually can be removed by surgery.
During surgery, the doctor takes off the clouded lens and, in most cases, puts in a clear, plastic lens. Cataract surgery is very safe. It is one of the most common surgeries done in the United States.
Glaucoma results from too much fluid pressure inside the eye. It can lead to vision loss and blindness. The cause of glaucoma is unknown. If treated early, glaucoma often can be controlled and blindness prevented. To find glaucoma, the eye doctor will look at your eyes through dilated pupils. Treatment may be prescription eye drops, oral medications, or surgery. Most people with glaucoma have no early symptoms or pain from increased pressure.
