The part of the eye that can sense light with the help of the light-sensitive pigment called rhodopsin is the rod photoreceptor cells in the retina. Rhodopsin is a protein found in the outer segment discs of rod cells, which are specialized for vision in low-light conditions (scotopic vision). When rhodopsin absorbs light, it triggers a phototransduction cascade that converts light into electrical signals sent to the brain for visual processing. Rod cells contain this pigment to enable night vision and the perception of black, white, and shades of gray. They are highly sensitive to light but do not mediate color vision, which is the role of cone cells in the retina
