Elimination of concentric myopic iridescence in optical lenses, by coating lens edges with acrylic paint after grinding. The procedure for eliminating concentric myopic iridescence in optical lenses (2) consists of coating the lens edges (4) after grinding with an opaque two-component acrylic paint (5) in a colour to match the main colour of the frame (1). The ground and cleaned lenses have their faces covered with adhesive masking tape, leaving only the edges exposed, and the paint is applied with a spray gun in three coats and left to dry for 12 hours before removing the tape.
