The astigmatic eye’s irregular curvature produces a doubling or ghosting effect in your vision.

How Does the Eye Function?

The eye functions on much the same principle as a camera. The iris or colored portion of the eye, acts as a shutter to regulate the amount of light coming into the eye. The cornea (the clear window of the eye) and the lens, located behind the pupil, serve to focus the light rays from the object viewed onto the retina in the back of the eye. The retina then transmits the “picture” of the object viewed to the brain where the object is then “seen”.
