Question

which of the following structures of the eye specifically focuses light on the retina? a.) lens b.) cornea c.) sclera d.) iris

Explanation:

The lens of the eye is responsible for focusing light onto the retina. The cornea also refracts light but the lens fine - tunes the focus. The sclera is the tough outer layer of the eye (the white part) and has no role in focusing light. The iris controls the amount of light entering the eye by adjusting the size of the pupil.

Answer:

A. Lens
