H52.1: Myopia

You are short-sighted. As a result you have problems seeing clearly in the distance.

The cornea is located at the front of the eye. It is transparent and curved. The curvature focuses light in the eye. This is vital to be able to see clearly.

The lens of the eye is located behind the pupil. The pupil is a round hole in the iris. The lens of the eye is transparent and lens-shaped like a magnifying glass. It lies in a fixed, transparent capsule made of connective tissue.

Rays of light enter the eye through the cornea and the lens. The image that you see then appears at the back of the eye on the retina. The light has to be focused just right for a person to see clearly.

In your case, the light is too focused to be able to produce a sharp image on the retina. This can happen, for example, if the eyeball is too long. It is also possible for the cornea or the lens to focus the light too much. This means that things you see far away are blurred or you have to strain your eyes a lot to see clearly.
