Myopia refers to the following vision problem: the eye can clearly see close objects, but distant objects look blurred. This occurs because the cornea has too much curvature, or the eyeball is too long. Myopia is often due to close-range visual stress, and it may be genetic too.
Generally, myopia occurs in school age children, but adults may also be affected, because of close-range visual stress or diabetes. A comprehensive optometric examination can diagnose myopia.
Prescription eyeglasses or contact lenses are normally used to correct myopia. Orthokeratology, also known as refractive therapy, is a non-surgical procedure - it gradually reshapes the cornea curvature. Eye laser surgery is the most common eye surgery, especially for treating adult myopia.
