Title: Combination of plural spectacle lenses varying in dioptry
Inventor: KOGASHIWA TAKESHI
IPC: G02B1/10
Filed: 1997-10-15
Abstract: PROBLEM TO BE SOLVED: To solve the problems of costs of production and management and the problems of appearance by forming lenses which all have the same curvature and varying the refractive indices of their materials, thereby varying their dioptry. SOLUTION: All of the lenses in the combinations of the plural spectacle lenses varying in the dioptry have the same curvature and the refractive indices of their materials vary, by which the lenses are so combined as to vary the dioptry. In such a case, the lens materials may be glass or plastics and are at present limited to the plastics as moldability is the problem. Plastics having various refractive indices are known and are available as such plastics. Then, if the combination of the plural lenses varying in the dioptry is desired to be obtd., such combination is obtd. with one or a smaller number of molds. Since the combinations of the lenses varying in the dioptry are obtd. by changing the refractive indices without changing their curvature, the curvature and edge thicknesses are both made uniform and the right and left balance and good appearance are obtd.
