Myopia refer to people when seeing at a distance, directional light is reflected by eye refraction and converges in retina
Before, so image clearly cannot be formed on the retina.Myopia can be corrected by concavees lens, logical
Diopter is often used to weigh the situation of ametropia.
Myopia generally all start because of excessive reading and other closely movable to eyes bring excessive
Regulation burden, normal human eye from see be changed at a distance see nearby time, imaging will in eye for object
Rear shifting, thus no longer fall on the retina, and the object seen is fuzzy.Therefore, in order to again
See that object, eyes need to make regulation, i.e. shrink ciliary muscle, allow crystalline lens become more convex, thus
Form higher refraction, allow the picture of object come back on retina.But, if closely used for a long time
Eye, the spasm of ciliary muscle be also possible to stimulate eyeball antero posterior axis elongation, thus formed cannot reverse near
