Multifocal glasses for presbyopes, have four plates horizontally arranged over specific width and exhibiting different correction powers for presbyopia, where correction powers of plates are progressive

摘要

The glasses have four plates (11-14) horizontally arranged over specific width and exhibiting different correction powers such as 0.5, 1.5, 2.5 and 3 dioptres, for presbyopia. The plates forming the glasses are arranged such that the correction powers of the plates are progressive. Two branches (1) of the glasses are fixed at a frame (2), where the glasses are multifocally fused and designed as progressive glasses or non-progressive glasses.
