what does the retina do

The retina is a crucial part of the eye responsible for capturing light that enters the eye and translating it into electrical signals that the brain interprets as images. It is a layer of specialized, light-sensitive cells located at the back of the eye. The retina contains photoreceptor cells, known as rods and cones, which play a key role in converting light into electrical signals for the brain to interpret. The macula, located in the center of the retina, is responsible for seeing fine details, while the peripheral retina helps with peripheral vision. The electrical signals generated by the retina travel through the optic nerve to the brain, where they are interpreted as the images we see. Any disease or damage to the retina can impact vision and cause changes in how images are perceived.
