Light enters the eye through the cornea. Ideally the eye diagram for digital signals would consist of two parallel lines with an instantaneous rise and fall times virtually invisible. In the real world even a reasonably good and quite acceptable digital signal will exhibit some amount of amplitude and timing variation which will show up as discrete lines that are not exactly where they belong but will nonetheless suffice.
The colored part of the eye the iris changes the pupil size to adjust how much light enters. Behind the iris is a clear elastic sheet called the lens that focuses the light further as it reaches the retina which absorbs light and relays the information to the optic nerve of the brain.
