MICROANATOMY

Detailed explanation-1: -The human retina has two types of photoreceptors to gather light namely rods and cones. While rods are responsible for vision at low light levels, cones are responsible for vision at higher light levels. The light levels where both are functional are known as mesopic.

Detailed explanation-2: -Which colors humans and other animals see depends on the light-sensing cells, or photoreceptors, in the eye. There are 2 types of photoreceptors: rods, which detect dim light and are used for night vision, and cones, which detect different colors and require brightly lit environments.

Detailed explanation-3: -Small cells called photoreceptors in the eye play a vital role in night vision and also affect how the eye sees color. Photoreceptor cells are located in the retina, which is the light-sensitive tissue that lines the back of the eye. There are two kinds of photoreceptor cells: cones and rods.
