ISO 12870:2016 specifies fundamental requirements for unglazed spectacle frames designed for use with all prescription lenses. It is applicable to frames at the point of sale by the manufacturer or supplier to the retailer. This International Standard is applicable to all spectacle frame types, including rimless mounts, semi-rimless mounts and folding spectacle frames. It is also applicable to spectacle frames made from natural organic materials. NOTE See Annex A for recommendations on the design of spectacle frames. ISO 12870:2016 is not applicable to complete custom-made spectacle frames or to products designed specifically to provide personal eye protection.
