What causes cataracts?

Dr. Ilan Cohen

Time: Most cataracts are caused by age related degeneration in the proteins in the lens of the eye. This degeneration causes the lens to lose its transparency. Cataract formation can be accelerated by trauma, steroids and other medications, diabetes, smoking, excessive ultraviolet light exposure and some other things. See your eye doctor if you suspect cataracts.

Many causes: Mostly aging, but diabetes, steroid use, and ultraviolet exposure all cause cataracts.

Usually age: If you live long enough, you will get cataracts--not everyone is bothered by cataracts or needs surgery to remove them. Cataracts can also be present at birth or may be caused by certain medical conditions, like diabetes. In addition, a cataract may be caused by an injury or as a side effect of other eye surgery.
Dr. Rajesh Khanna

Age Causes: A cataract is a cloudy area in the lens of your eye. Normal eye lenses are completely transparent, allowing light to pass freely to the back of the eye. Once a cataract starts to develop, your eye’s lens will gradually become more opaque, causing less light to reach your retina. Around 50% of americans between the ages of 65 and 74 have cataracts.
