Definitions:

Cone Cells

Cells in the eye's retina called photoreceptors are crucial for seeing colors and achieving sharp vision in well-lit environments.

Binocular Vision

Vision using two eyes at the same time; responsible for depth perception when the visual fields of the eyes overlap.

Rhodopsin

A light-sensitive receptor protein found in the rods of the retina, critical for vision in low-light conditions.

Photoreceptor

Sensory receptor that is sensitive to light—for example, rods and cones of the retina.
