The present invention relates to improved adhesion of the layer structure (1) to the convex surface of the lens (10). After heat forming the layer structure, the curvature direction of the layer structure is reversed. The layer structure is then attached to the lens surface by successively pressing the layer structure 1 against the lens surface, starting at the contact point between the convex surface of the layer structure and the concave surface of the lens. Then, the curvature direction of the layer structure is reversed again to recover the curvature direction generated by the heating molding. The stress in the layer structure is reduced and the layer structure can be assembled with the lens without defects.n n n n Lens, layer structure attachment method, spectacle lens |
