Index 1.67 is a lens material that is 35% thinner than standard. The thickness of the lens is also influenced by the diameter of the eyeglass lens, which depends on the size of the frame and the interpupillary distance. For high correction values, it is worth choosing frames with a smaller lens area. Some lenses have the METS optimization option – fitting the smallest required diameter. We recommend optimization for positive correction values.
Additional reduction in lens thickness, excellent image reproduction, and a more natural look of the eyes with "plus" lenses - reduction of eye magnification in glasses.
Standard "white" spectacle lenses without colored sun filters.
Anti-reflective coatings with additional layers for easier cleaning, repelling dirt and dust. An additional hardened layer ensures longer use of glasses.
