- If The Person Provides To Itself Good

- if the person provides to itself good sight with- Power concave, convex or lenses, it - , that it(he) keeps constantly certain degree - refractions which in other conditions would not be kept Those. Unique result of such situation follows - To give deterioration of a condition. Experience shows, that is usual and Occurs(Happens). " [16, .35]. It is necessary to consider and such fact. That a refraction of an eye - When there is no constant, does not allow to write out exact - on glasses(spots). It is no wonder, that to some people and not It is possible to pick up glasses(spots) to which their eyes would reconcile. - The constancy of a refraction results(brings), besides to that - which we can observe in statistical data about Prevalence of those or other kinds of infringement of sight. According to theory , the reason of occurrence of anomalies - the pressure(voltage) is. At this effort to see The removed objects, at - near. Glasses(spots) only Correct(Adjust) anomaly of a refraction, but do not eliminate(erase,remove) its(her) reason Occurrence.
