Abstract

PURPOSE:To prevent the pupil from being located around the boundary line of both lenses even when a lens for near use is used, by constituting so that the position of a nosepiece can be varied up and down against a spectacle frame, and the upper and lower relative position of the pupil position and the spectacle lens can be varied. CONSTITUTION:A lens 2 for both far and near use, for instance, a concave lens part 2' for far use and a convex lens part 2'' for near use are formed separately or in one body, and are mounted to a spectacle frame 1. A guide 3 is provided on the spectacle frame 1, a slide lever 4 which is inserted into this guide 3 and is able to freely slide up and down is provided in a slide system, and also a nosepiece 5 is connected with both ends of this slide lever, respectively. Since the nosepiece is constituted so that its position can be varied, such an unnatural trouble as cast an upward glance or used the lower surface in the past is removed, and eyes are not fatigued.
