The retina is a thin layer of tissue located at the back of the eye. It plays a crucial role in vision by converting light that enters the eye into electrical signals. These signals are then sent to the brain, where they are processed to create the images we see. The retina contains special cells called rods and cones, which help us see in different lighting conditions and perceive colors. When light hits the retina, it triggers these cells to react, sending information through the optic nerve to the brain. Any damage to the retina can lead to vision problems, making it essential for maintaining good eye health. Regular check-ups with an eye doctor can help detect issues early.
