Light interacts with the eye to form images from "summary" of Physics of the Human Body by Richard P. McCall
The process of seeing begins with light entering the eye. This light passes through the cornea, the transparent outer covering of the eye. The cornea bends the light rays and helps focus them onto the lens. The lens further refracts the light to focus it onto the retina, which lines the back of the eye. The retina is a layer of tissue that contains cells sensitive to light. When light reaches the retina, it triggers a series of electrical and chemical signals that travel to the brain via the optic nerve. These signals are processed in the brain to form visual images. The lens of the eye plays a crucial role in focusing light onto the retina. The lens changes its shape to adjust the focus, allowing...
