The lens must be clearfor the retina to receive a sharp image.

When asked about spectacle use on patient surveys, currently close to 97% of patients reply they are spectacle independent.
As it progresses reading vision can suffer along with a change in spectacle number.

Cataract surgery is the removal of the natural lens of the eye (also called "crystalline lens") that has developed an opacification, which is referred to as a cataract.
Metabolic changes of the crystalline lens fibers over time lead to the development of the cataract and loss of transparency, causing impairment or loss of vision.
