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.
Very easy to **keep clean** and **durable** eyeglass lenses.
Hoya Hi-Vision Longlife is an advanced coating from HOYA. It provides the highest level of frame transparency and lens surface protection. It is **seven times harder** than standard coatings. It has the best **dirt, dust, and water-repellent** layers.
Classic "spherical" lens construction.
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.
Advanced HOYA spectacle lenses.
Increased mechanical resistance. Optical material recommended for "rimless" frames. Can be used in frameless mounts.
