Cornea

The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. The cornea is a continuation of the sclera, or the white of the eye, and is made of collagen fibers laid down in such a fashion that it is transparent and able to admit light. Together with the lens, the cornea refracts light, accounting for approximately two-thirds of the eye’s total optical power.
