The cornea of the human eye has refractive index 1.38, while the eye’s lens has a graduated index in the range 1.38 to 1.40; use 1.39 for this problem. For the aqueous humor between cornea and lens, n = 1.34. Find the angle through which light is deflected at the first surface of
(a) the cornea
(b) the lens, if it’s incident at 20° to the normal at each surface. Your result shows that the cornea is the dominant refractive element in the eye.
