To provide a processing method for lenses of frameless eyeglasses, capable of increasing the yield rate in the assembly line of frameless eyeglasses, and substantially reducing the breakage of eyeglasses by a user in unforeseen situations, and to provide frameless eyeglasses that use this method.

A surface part of the lens, around the spot where a fitting hole and/or a fitting channel for fixing metal fittings for fixing the lenses of frameless eyeglasses is provided, is ground to a predetermined depth, forming a convex part. Resin for reinforcing the lenses is injected into the convex part, and hardened, thereby forming reinforcing resin parts 5a and 5b, and then the fitting hole or the fitting channel is processed. Flexible resin is used for the reinforcing resin parts and the impact resistance is improved.
