Understanding the Retina
The retina is the light-sensitive tissue lining the back of our eye. Light rays are focused onto the retina through our cornea, pupil and lens. The retina converts the light rays into electrical impulses that travel through the optic nerve to our brain, where they are interpreted as the images we see. A healthy, intact retina is needed for clear vision.
If the normal connection between the retina and the brain is damaged, transmission problems will result.
