How is the sun so damaging? Well, we see images because photoreceptors, cells also known as rods and cones located at the back of the retina, convert the light into electrical impulses that the brain uses to determine the image we see. But when strong light, like the sun's rays, hits our eyes, a series of chemical reactions occur that damage and often destroy these rods and cones. When this happens, which is known as solar retinopathy, our eyesight becomes blurry. Sometimes, if the damage is too great in one area, our vision can be completely impaired.
