Myopia (Nearsightedness)
Nearsightedness is caused by a change in the shape of the eyeball so that it is egg-shaped instead of round. This egg-shaped eyeball focuses light a little in front of the retina instead of directly on it resulting in blurry vision. Myopia is a common condition affecting between 30 to 40 percent of the American population.

Detached Lens
A detached, or dislocated, lens means that the lens has shifted from its normal position (centered behind the pupil). If the dislocation is moderate, the problem may be corrected with glasses. A severe lens dislocation may require surgery to correct.

Detached lenses are rare in the general population. They are often caused by a blow to the eye. The condition is much more common among people with certain diseases involving connective tissue such as Ehlers-Danlos syndrome and Marfan syndrome.

A close-up photograph of a normal eye is seen. In the center of the eye is a black circle labeled pupil. The pupil is surrounded by a larger brown-colored circle labeled iris. The rest of the eyeball is white-colored and labeled sclera.

A close-up photograph of an eye with a detached lens is seen. In the center of the eye, the lens is off center so that only about half of the circular pupil area is covered by the lens. The part of the pupil area not covered by the lens looks black.
