Description
Long sightedness corrected with convex lens, computer illustration. In long sightedness the focal point for incoming light (red lines) is behind the retina (orange), causing difficulty focusing on near objects. This may be a result of the eyeball being shorter than it should be, or problems with the lens (dark blue) or cornea. It can be corrected by placing a convex lens (right) in front of the eye.
