The device and method in order demonstration to do the effect of lens coating for acid resisting

摘要

Acid resisting in prescribing the spectacle lens of the patient (AR) the effect of coating, it is the device, and method in order demonstration to do in the patient. As this device, has the rear attaching kit for the refraction body or the refraction body, the spherical lens whose degree is strong at least and the spherical lens whose degree is weak having, high refractive index (IR) is provided, high optical transmission (LT) ratio reflection per low surface area (RPS) it features that the acid resisting coating which causes with ratio has been administered. Furthermore, this device, possessing the observation tube of the refraction body, installation and removal possibly includes the installation possibility, one filter at least with the alignment with visual inspection. In order for the filter with the observation tube and the alignment being done either the spherical lens whose degree is strong and the spherical lenses whose degree is weak combining, when being arranged, AR coating processing is not to actualize net LT value and the net PRS value which correspond to the lens which is used for the spectacle lens of the patient, to possess IR value, LT value, and PRS value it is selected.
