visual pigment

Visual pigments are light-sensitive molecules located in the cells of your eyes, specifically in the retina. They consist of a protein called opsin and a light-absorbing molecule called retinal. When light enters the eye, it interacts with these pigments, causing a change that triggers a chemical signal sent to your brain. This process allows you to perceive images and colors. Different types of visual pigments are tuned to detect various wavelengths of light, enabling you to see a wide range of colors and brightness levels.
