Rimless eyeglasses
Abstract:
Rimless eyeglasses are provided, which do not produce loosening in a connecting area between an eyeglass lens and a lens fixing portion, and which also allows for the easy attachment or removal of a lens. The rimless eyeglasses include eyeglass lenses and as eyeglass components, a metallic end-piece member and a metallic bridge member, having a lens fixing portion fixedly attached to the eyeglass lens and a connecting portion connected to a temple or a bridge. The lens fixing portions of the metallic end-piece member and the metallic bridge member have cylindrical leg portions, each inserted into a lens hole formed in the eyeglass lens. Spiral-shaped grooves are formed in the outer peripheral faces of the leg portions. An adhesive is injected into the spiral-shaped grooves.
