CATARACTS
What Causes Cataracts?
Cataracts happen when protein builds up in the lens of your eye, making it cloudy. This prevents light from passing clearly through the lens, causing some loss of vision. New lens cells form on the outside of the lens, and the older cells are compacted into the center of the lens, forming the cataract.
Types of cataracts include:
Other things that can raise your risk of getting cataracts include cigarette smoke, air pollution, and heavy drinking.
Cataracts usually form slowly and cause few symptoms until they noticeably block light. Symptoms can include:
that is cloudy, blurry, foggy, or filmy
Progressive nearsightedness in older people often called “second sight” because although their distance vision is getting worse, they may no longer need reading glasses
Changes in the way you see color
Problems driving at night such as glare from oncoming headlights
Problems with glare during the day
Double vision
Sudden changes in your glasses prescription
How Are Cataracts Diagnosed?
You will get an eye exam to test how well you can see (remember to bring your glasses or wear your contacts to the appointment). Your doctor will also dilate your pupil to examine the lens and other parts of the eye.
How Are Cataracts Treated?
If your vision can be corrected with eyeglasses or contacts, your doctor may prescribe them.
If your vision cannot be corrected with glasses or contacts and cataracts interfere with your daily life, you may need cataract surgery.
