Nearsightedness
(myopia) occurs when your eyeball is too long or your
cornea curves too much. For nearsighted people, images enter the
front of the eye and focus directly in front of the retina. This
results in distant objects being blurry, while near objects appear clearly.
Nearsightedness
most often begins in the pre-teenage years. Heredity and, possibly,
environmental factors cause nearsightedness. Eyeglasses or contact
lenses improve vision by properly focusing distant objects clearly on
the retina.
