How the Eye Works
Light is focused onto the retina by the clear dome over the eye (the cornea) and the lens, which lies behind the iris (the colored part of our eye). The retina lines the back of the eye like wallpaper. It senses or "sees"the light by converting the light signals into electric/chemical signals that are understood by the brain. The central part of the retina is called the macula. The macula is responsible for most of our ability to read and see fine detail.
