Nearsightedness | Myopia |

Myopia In simple myopia (nearsightedness) without astigmatism, distance vision is blurred while near vision may be clear. This occurs because light is focused too far forward or in front of the retina secondary to one of the following problems:

The eye is too large.

The cornea (clear window at the front of the eye) is too steep and thus
pulls the focus of light in front of the retina.

The lens in the front of the eye is too strong and pulls the focus
of light in front of the retina.

In myopia, vision can be corrected by altering the curve on the front surface of the cornea to make the curve flatter. Light then focuses further back in the eye on the retina.

Currently, it is not possible to alter the clear lens of the eye except to remove the lens if it becomes a cloudy lens (cataract) or if a person has very severe myopia or nearsightedness.

One new technique for eyes with very severe myopia (or even for eyes that are extremely farsighted as described below) is to place an artificial lens inside the eye in front of the normal lens to help with the focusing. This is currently being investigated.
