retinal structure

The retina is a thin layer of tissue at the back of the eye that captures light and converts it into electrical signals. It contains specialized cells called photoreceptors—rods for vision in dim light and cones for color and sharpness. These cells detect light patterns and send signals through nerve pathways to the brain, where they are interpreted as images. The retina also has supporting cells that nourish and maintain the structure. Its intricate layered organization allows us to perceive detailed, colorful visual information essential for sight.
