The humors keep the eye inflated, refract light, and provide nutrients to the inner surface of the eye. Functions of the Complete Eye o Light passing through a concave surface diverges. Light passing through a convex surface converges. o Converging light rays cross at the focal point and are said to be focused. o The cornea, aqueous humor, lens, and vitreous humor all refract light.
