|Let us now begin to look at specific types of eye conditions and how they would affect normal vision in terms of functional losses. First, a park scene as perceived with normal vision. If we were to look at the interior of a normal eye, with a microscope, we would see that the eye is made up of two distinct types of cellular structures which are shaped like rods and cones.
