Name the defect of vision which makes the eye-lens cloudy resulting in blurred vision.
Cataract is the defect of vision which makes the eye-lens cloudy, resulting in blurred vision.
Explanation
Cataract is a defect of the eye in which the eye-lens of a person become progressively cloudy or opaque resulting in blurred vision.
It usually comes in old age and develops due to the formation of a membrane (clumps of protein) over the eye-lens.
It can't be corrected by any type of spectacles lenses, rather it can be corrected by the surgery in which the opaque lens is removed, and a new artificial lens is inserted in its place.
