Myopia (short-sightedness)

In a short-sighted or myopic eye the eye grows too long, and rays of light entering it from a distant object are focussed at a point in front of the retina, which means that the image appears blurred.

Light from a near object however, is focussed at the retina, which means that the eye can see near objects, even though objects further away are blurred.

The focussing ability of an eye is determined by the curvature of the cornea (front surface), the power of the crystalline lens, and its overall length.

Myopia is the most common eye disorder. Its prevalence is increasing throughout the world at an alarming rate in what has been termed the “myopia epidemic”. See also Myopia control.
