Know about Cataract
Cataract is a degenerative condition of the eyes which generally occurs due to aging. There is opacification of the lens (part of the eye where light rays focus for vision), thus causing problems of vision. As the cataract progresses, one has progressively reduced vision. Ultimately a person may be able to see only 1 or 2 fingers in front vaguely and the rest all appears blurred. This is technically called as count finger vision.
