Cones, on the other hand, are found in a really high concentration near the fovea. So at the fovea, there are a whole bunch of cones. And in the periphery of the eye, there might be a few cones every now and then. WebThe Retina. The retina is a light-sensitive layer at the back of the eye that covers about 65 percent of its interior surface. Photosensitive cells called rods and cones in the retina convert incident light energy into signals that are carried to the brain by the optic nerve. In the middle of the retina is a small dimple called the fovea or fovea centralis. react if condition in html
