Retinal pigments are light-sensitive molecules found in the retina, the thin layer of tissue at the back of the eye. These pigments play a crucial role in vision by absorbing light and initiating the process of converting it into electrical signals that the brain can interpret. The most well-known retinal pigments are rhodopsin, found in rod cells, and photopsins, found in cone cells. There are different types of retinal pigments, each sensitive to specific wavelengths of light. Rhodopsin is highly sensitive to low light levels, enabling night vision, while photopsins allow for color vision in brighter light. Together, these pigments help us perceive the world around us.
