Myopia

Myopia, sometimes referred to as nearsightedness, is a vision condition in which close objects are seen clearly, but objects farther away appear blurred.  Nearsighted individuals may want to squint or strain when trying to see far objects clearly.

Myopia occurs due to an irregularly shaped cornea: If the eyeball is too short or if the cornea has too much curvature.

This causes light rays to focus in front of the retina, rather than directly on the retina. The light entering the eye is not focused correctly and distant objects look fuzzy. Generally, nearsightedness first occurs in school-age children. Because the eye continues to grow during childhood, it typically progresses until about age 20. However, myopia may also develop in adults.
