In this diagram, five incident rays are drawn along with their corresponding refracted rays. The variable opening (or pupil) of the. The eye is remarkable in how it forms images and in the richness of detail and color it can detect. Actually, normal vision should be called “ideal” vision because nearly one-half of the human population requires. Review the lens/mirror equation from the Reflection section. Review the terms focal point, focal length, object distance, image distance, concave, convex, converging, and diverging from the Reflection section.
