STRUCTURE OF PROGRESSIVE LENSES FOR FAR-SIGHTED

摘要

A structure of a progressive lens for farsightedness is provided to improve eye sight of a user by enabling the user to change the mode of the progressive lens between nearsightedness and farsightedness with a simple push button. Glass frames(1,2) are integrated with a bridge(3). Temples(4,4') are coupled with both ends of spectacles via hinges(5). Push buttons(7,7') are exposed from liquid storage tanks(8,8'). A first through-hole(9) is formed from the frames to the bridge. A first hose(10) is inserted into the first through-hole. A second through-hole(9') is formed below the glass frames. A second hose(10') is inserted into the second through-hole. Silicon lenses are attached to fixed lenses on a lens holding portion of the glass frames. A lower portion of the silicon lens for nearsightedness correction is coupled with one end of the first hose. The end portion of the second hose is attached to the lower portion of the silicon lens. The fixed lenses are inserted into the silicon lenses.
