Cataract is an eye disease. Protein may build up in the lens of the eye and make it cloudy. Light is not able to pass clearly through the lens, due to which some eyesight may be lost. Cataracts are of different types, including age related cataract, congenital cataract, secondary cataract and traumatic cataract.
Cataracts make the vision cloudy or blurry and generally occur in people above 60 years of age. In older adults, this eye disease is more common and can be treated by a good eye doctor.
Chances of getting cataract increase with drinking heavily, pollution in the air and smoking cigarettes.
Cataracts form quite slowly and the person may not even know about it till the cataracts begin blocking light. Symptoms of cataract include filmy, foggy, blurry and cloudy vision, trouble with contact lenses or eye glasses, nearsightedness in older adults, double vision in the eye that is affected, changes in seeing colors, issues with glare during day time and problems while driving during night time.
