Trace the path of light as it enters the eye. Your answer should include the major structures of the eye

What will be an ideal response?

The cornea is the rounded, transparent covering over the front of your eye. As the light waves pass through the cornea, its curved surface bends, or focuses, the waves into a narrower beam.

The pupil is a round opening at the front of your eye that allows light waves to pass into the eye's interior.

The iris is a circular muscle that surrounds the pupil and controls the amount of light entering the eye. The iris muscle contains the pigment that gives your eye its characteristic color.

The lens is a transparent, oval structure whose curved surface bends and focuses light waves into an even narrower beam. Th e lens is attached to muscles that adjust the curve of the lens, which, in turn, adjusts the focusing.

The retina, located at the very back of the eyeball, is a thin film that contains cells that are extremely sensitive to light. These light-sensitive cells, called photoreceptors, begin the process of transduction by absorbing light waves.
