A Cataract is a dense or blur or cloudy area in the lens of the human eye. Our eye lens is the clear part of the eye which plays an important role to focus lights. When adults get older, cataracts are a very common problem. Also cataracts are seen in young adults & kids too which is very rare & common now.
Cataracts are mainly caused by an increase of proteins in the eye lens, which gets converted into protein clumps. These protein clumps block lights from passing clearly via the eye lens, which disrupt the normal vision of the eye.
Cataracts are a very common disease majorly for old adults to lose vision. The best way to remove cataracts and restore the eye vision is through only Cataract surgery. An eye expert called an Ophthalmologist removes the clouded lens and replaces it with an IOL (Intraocular lens or artificial lens) which remains in the eye permanently.
