Description | The aim is to introduce the problems of accurate lens grinding, explanation of the basic principles of the eye - glasses, explanation methods of measuring of input data and consequences described inaccurately of glasses correction. Research is focused on the frequency exceeding the values of decentralization optical centers of the lenses to the centers of the pupil over the threshold at which the spectacle correction was not tolerated in individuals. For toric lens is examined if there was no twist axis cylindrical component of the tolerated threshold. The work is finished by comparing the input values of measurement, comparing the values pupillary distance, measured by three methods - direct method, PD meter and software Omega smart mirror. |
