MICROANATOMY

Detailed explanation-1: -There are two types of photoreceptors involved in sight: rods and cones . Rods work at very low levels of light. We use these for night vision because only a few bits of light (photons) can activate a rod. Rods don’t help with color vision, which is why at night, we see everything in a gray scale.

Detailed explanation-2: -Rods are a type of photoreceptor cell present in the retina that transmits low-light vision and is most responsible for the neural transmission of nighttime sight. Rods have a singular photopigment, rhodopsin, which utilizes the protein scotopsin and the Vitamin A-derived cofactor, retinol.

Detailed explanation-3: -There are two types of photoreceptor cells in the retina: cones and rods. The cones are responsible for sharp color vision in daylight. The rods provide vision in dim light.
