Summary
A cataract is a condition in which the eye becomes cloudy and opacified, affecting ones s vision. Cataracts can be congenital, meaning people are born with them. Congenital cataracts usually result from congenital infections or some genetic or metabolic conditions. Cataracts can also be acquired, usually in individuals with advanced age. Acquired cataracts develop slowly and can occur in one or both eyes. Over time, they become more dense and yellowed and can eventually cause blindness. Common risk factors for acquired cataracts include old age, excessive alcohol consumption, smoking, eye infection, or trauma. Risk is also increased in people with Diabetes Mellitus or in people whose eyes are exposed to radiation such as ultraviolet.
