Quizplus · Accepted Answer

The sclera, also known as the white part of the eye, is a tough, fibrous tissue that extends from the cornea to the optic nerve at the back of the eye. Its primary function is to maintain the shape of the eyeball, providing structural support and protection for the inner components of the eye. It does not play a direct role in light accommodation, focusing light rays on the retina, or controlling and focusing light entering the eye; these functions are primarily performed by the lens and the iris.
