What are cataracts ?
Cataracts are a clouding of the crystalline lens of the eye. This in turn affects vision. Cataracts form for many reasons but the most common is age. It is normal for people over the age of 65 to have some mild form of cataracts. Causes of Cataract development include age, steroid use, trauma, radiation, or as a result of other eye conditions such as glaucoma. Cataracts can occur in one or both eyes, sometimes years apart, but it cannot spread from one eye to another.
