Long sight and its correction
This animation shows a long sighted eye. Long sight occurs either because the eye lens is too weak or the eyeball is too short. In each case the image is formed behind the retina and the person therefore sees a fuzzy view of the object.
Short sight can be corrected using a convex lens.
