Give an account on the characteristics and features of cataract
Answer:-
A cataract is a clouding of the lens of the eye that affects vision. The lens, located behind the iris and pupil, normally allows light to pass through to the retina and produces clear, sharp images. However, as we age or due to other factors, the proteins in the lens can clump together and cause the lens to become opaque, leading to vision problems.
Symptoms of a cataract include blurred or hazy vision, increased sensitivity to glare and bright lights, faded or yellowed colors, and double vision in one eye. Cataracts can also cause frequent changes in prescription for eyeglasses or contacts.
Cataract surgery is a common and safe procedure to remove the cloudy lens and replace it with an artificial lens. The surgery is typically performed on an outpatient basis and most people experience improved vision within a few days after the procedure.
In conclusion, cataracts can significantly affect vision, but surgical removal and replacement with an artificial lens can restore clear vision and improve quality of life. Regular eye exams can help detect cataracts early and prevent vision loss.
