rod photoreceptors

Explanation:

The retina of the eye has 2 types of sensory receptors or photoreceptors. They are the rod cells and the cone cells. The rod cells mostly found at the outer edge of the retina of the eye, which are numerous and more sensitive compared to the cone cells. The cone photoreceptors are found in the macula.

The rod photoreceptors are responsible for night vision mainly and function in dim light or less intense light, while the cone receptors are responsible for color sensitivity.
