Problem 4: The human eye can be approximated by a two-lens optical system. Light enters the eye and first travels through the cornea. The cornea has a fixed focal length of 4.16666 cm. Next, light travels through the center of the crystalline lens which has a focal length that can change. For healthy eyes, the crystalline lens is set 0.50000 cm behind the cornea and can vary in focal length from 9.0000 cm to 16.5000 cm. The retina acts as an image screen upon which real images are focused for processing by the brain. The retina is 3.0000 cm behind the crystalline lens.
