Solution

The correct option is D
Refracts light entering the eye onto the lens and focuses images onto the retina

Cornea is a transparent layer of tissue, continuous with the sclerotic that forms the front part of the vertebrate eye over the iris and lens. The cornea refracts light entering the eye onto the lens, thus assisting in focusing images onto the retina.
