Light-sensitive cells

Light-sensitive cells, called photoreceptors, are specialized cells in the retina of the eye that detect light and convert it into electrical signals. There are two main types: rods, which are highly sensitive and help us see in low light, and cones, which detect color and provide sharp, detailed vision. These cells work together to allow us to perceive the world visually. When light hits these cells, they trigger signals that are sent to the brain via the optic nerve, enabling us to interpret what we see.
