Definitions:

Ciliary Muscles

A ring of smooth muscle in the eye's middle layer that controls the lens's shape for focusing.

Pupil

Circular opening in the iris through which light enters the eye.

Rods

Photoreceptor cells in the retina of the eye, highly sensitive to light, and responsible for vision under low light conditions.

Optic Disc

The point of exit for ganglion cell axons leaving the eye. Because there are no rods or cones overlying the optic disc, it creates a blind spot in visual fields.
