[Optic correction of myopia].

Correction of myopia by optics is still the most widely used method of visual rehabilitation. It raises visual acuity to levels that permit a normal life in a world where vision is particularly important. This success of glasses and lenses is most perfect for mild or moderate myopia. For subjects with severe myopia glasses are not without problems and contact lenses are preferable, but the results sometimes remain mediocre due to organic disorders resulting from excessive lengthening of the eyeball.
