photoreceptors

Photoreceptors are specialized cells in the eyes that detect light and enable vision. There are two main types: rods and cones. Rods are sensitive to low light and help us see in dim conditions, while cones are responsible for color vision and function best in bright light. Together, these cells convert light into electrical signals that are sent to the brain, allowing us to perceive images. Photoreceptors play a crucial role in how we interact with our visual environment, helping us navigate and understand the world around us.
