A cataract is a clouding of the lens in the eye which leads to a decrease in vision. Cataracts often develop slowly and can affect one or both eyes. Symptoms may include faded colors, blurry vision, halos around light, trouble with bright lights, and trouble seeing at night.
Most cataracts develop when aging or injury changes the tissue that makes up your eye's lens. Some inherited genetic disorders that cause other health problems can increase your risk of cataracts. Cataracts can also be caused by other eye conditions, past eye surgery or medical conditions such as diabetes.
What happens if cataracts are left untreated?
Risks of Untreated Cataracts. Left untreated, cataracts can lead to vision impairment, vision loss, and even blindness. ... Cataracts can form in one eye or both, and they can progress differently in each as well. One eye may be worse than the other or progress faster, for instance.
When symptoms begin to appear, you may be able to improve your vision for a while using new glasses, strong bifocals, magnification, appropriate lighting or other visual aids. Think about surgery when your cataracts have progressed enough to seriously impair your vision and affect your daily life.
Many people consider poor vision an inevitable fact of aging, but cataract surgery is a relatively painless procedure to regain vision. Cataract surgery is very successful in restoring vision. In fact, it is the most frequently performed surgery.
