photoreceptor cell

Photoreceptor cells are specialized cells in the retina of the eye that detect light and convert it into electrical signals, which are then sent to the brain for visual processing. There are two main types: rods, which are sensitive to dim light and help with night vision, and cones, which detect color and detail in well-lit conditions. These cells contain light-sensitive molecules that trigger chemical changes when exposed to light. This process allows us to perceive images, colors, and brightness, enabling vision across various lighting environments.
