LASIK for short-sightedness
Myopia is when people see near objects more clearly, but distant objects are blurry.
It occurs when light rays entering the eye are focused in front of the retina instead of directly on it.
Myopia is usually a result of the curvature (power) of the cornea being too strong or the length of the eyeball being too long.
Myopia is often inherited; it usually starts in childhood and typically stabilizes in the late teens or early adulthood.
