Retinal cells are specialized cells located in the retina, the light-sensitive layer at the back of the eye. They play a crucial role in converting light into electrical signals, which are then sent to the brain for visual processing. The main types of retinal cells include photoreceptors, bipolar cells, and ganglion cells. Photoreceptors are further divided into rods and cones. Rods are responsible for vision in low light, while cones enable color vision and detail in brighter conditions. Together, these cells work in harmony to help us perceive the world around us.
