retina definition and meaning

What is "retina"?

The retina, located at the back of the eye, is a thin, light-sensitive layer that plays a crucial role in vision. It contains specialized cells called photoreceptors, including rods and cones, which convert light into electrical signals. These signals are then transmitted to the brain through the optic nerve, where they are processed and interpreted as visual information. The retina's intricate structure and arrangement of photoreceptor cells enable the perception of colors, shapes, and details, forming the foundation of visual perception. It acts as a vital sensory component, allowing us to see and perceive the world around us.
