Quizplus · Accepted Answer

The lens is responsible for changing shape to focus incoming light onto the retina, enabling clear vision. The cornea helps to refract the incoming light, while the retina contains photoreceptor cells that convert the light energy into electrical impulses for the brain to interpret. The fovea is a small depression in the retina that contains a high concentration of photoreceptor cells for sharp, detailed vision.
