Glasses only correct anomaly of a refraction, but do not eliminate the reason of its{her} occurrence. Надев glasses, short-sighted on former on a habit will strain to see far located subjects, and гиперметропик and in glasses will continue to put effort to see, for example, letters. Thus, sight will continue to worsen and in glasses. Many people, likely, noticed, that after once надели glasses, sight without them it became appreciable worse. And it not the subjective sensation caused by transition from good sight in glasses to bad without them. Check at the oculist confirms, that sight actually has worsened. In result to the person new glasses with stronger lenses leave. As the pressure{voltage} continues to take place, moreover with accumulation of effect in due course it is possible to notice, that frequency of change of glasses on new grows every year. Подробнее...
