<p>A method of making a lens (10) comprising a functional laminate (14) bonded to a primary part (12), the method comprising: providing a moulding machine comprising a mould having moulding surfaces (102, 126, 128, 130) defining a mould cavity (104) including a convex moulding surface (126) for defining a front surface (18) of the lens, inserting a functional laminate (14) in the mould cavity, creating a seal between the functional laminate (14) and said convex moulding surface (126), injecting a molten thermoplastic resin into said moulding cavity (104) to form said primary part without said molten material intruding between the functional laminate and convex moulding surface, at a temperature in the cavity (104) sufficient to cause the primary part and the functional laminate to fuse together by welding into a permanent bond and allowing said molten material to solidify thereby forming said lens. <IMAGE></p> |
