There are 2 types of photoreceptors in the. Rod cells are highly sensitive to light and function in nightvision whereas cone cells are capable of detecting a wide spectrum of light photons and are responsible for colour vision. Stimulated by light energy. While cone photoreceptors detect color through bright light rod photoreceptors are sensitive to low-light levels. Highly sensitive to minimal light allows us to see at night shapes and movement rhodopsin split into opsin and retinene in photon of lightopsin and retinene turn ATP into ADP and combine back to make rhodopsin.

In humans three classes of cones confer robust color vision. Cones are active at higher light levels photopic vision are capable of color vision and are responsible for high spatial acuity. Cone photoreceptors are morphologically and functionally distinct from rods and express several types of visual pigments or opsins whose spectral sensitivity varies based on the cones subtype. These properties reflect the fact that the rod and cone systems the receptors and their connections within the retina are specialized for. They act as a type of pupil protecting the rhabdom in bright conditions by absorbing light.
