Name one defect of vision (or eye) which cannot be corrected by any type of spectacle lenses.
Cataract is one of the defects of vision that cannot be corrected by any type of spectacle lenses.
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.
