Final answer:The cornea is the first structure in the eye to make contact with light. It plays a crucial role in bending incoming light rays for proper vision.Explanation:It refracts incoming light rays so that they converge precisely on the retina.After passing through the cornea, light then travels through the lens, which refracts light further to focus images on the retina.The iris and pupil also play roles in adjusting the amount of light entering the eye.The retina is a layer of photoreceptors cells and glial cells within the eye that captures incoming photons and transmits them along neuronal pathways as both electrical and chemical signals for the brain to perceive a visual picture....
