METHOD OF MANUFACTURING A PAIR OF SPECTACLE LENSES FOR THE IMPROVEMENT OF THE VISUAL PERFORMANCE IN PATIENTS WITH KERATOCONUS, AS WELL AS A SET OF SPECTACLE LENSES

摘要

In the method for the eyelashes of visual performance of the manufacture for improving the keratoconus with hardness or soft contact lens correction, using one group of light passing glasses, wherein the part being located on the downside of light passing glasses is positive intensity and negative intensity respectively. Firstly, the eyes of patient have the keratoconus of minimum level. Next, according to the normal rule of subjective refraction, it is first determined best spherical glass, then, from one group of light passing glass, when patient watches optical type w, according to this method, best spherical glass is determined by saving the different light passing glass of described group of light passing glass. Two eyes. Then this point is repeated to the eyes of another patient. In refracting process, another eyes can be labeled with branding. Later, spectacle glass is manufactured with intensity identical with the glass found, and is equal to the segment of the sum of the intensity of the segment of institute's gated optical glass and the intensity of spherical glass with intensity.
