Definitions:

Rod Function

The role of rod cells in the eye, primarily responsible for vision at low light levels (scotopic vision).

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.
