Abstract
This invention relates to a method for working an auxiliary spectacle lens to be added to the spectacles in use, in more details, pertaining to a technique for efficiently working such lens that is light in weight and easy to be stably mounted in front of the lenses of the spectacles in use. That is to say, this method comprises the steps of opening a slit of a size on a fringe portion of an unworked auxiliary lens made of synthetic resin by means of a shearing tool and tightly mounting a joint piece with a pigeon-eyed hole opened therein or that provided with bent portions to be suspended onto the lenses of the spectacles in use into said slit. Accordingly, this invention enables even an optical shop of a small scale to deal with such working just by obtaining an unworked auxiliary lens made of synthetic resin, a joint piece and a shearing tool of a simple structure.
