Title: LENS FIXATION METHOD, HEAT CLENCHING TOOL, AND LENS FIXATION DEVICE
Abstract:
A lens fixation method includes: bringing a first pressing part into contact with a base part of a heat clenching flake-shaped part before a lens clenching tool makes contact with a tip part of the heat clenching flake-shaped part; pressing the outer peripheral part of the heat clenching flake-shaped part thereafter; and pressing the tip part of the heat clenching flake-shaped part in the axial direction of a lens frame toward a clenching area on the lens by a second pressing part.
