Photoreceptor Cells
Photoreceptor cells 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 enable us to see in low light conditions, and cones, which function best in bright light and allow us to see color and fine detail. When light hits these cells, they generate signals that travel to the brain via the optic nerve, enabling us to perceive images and colors. Photoreceptors are essential for vision and help us interpret our surroundings.
