Index 1.50 is the standard thickness of eyeglass lens material.
The thickness of the lens is also influenced by the diameter of the eyeglass lens, which depends on the frame size and pupillary distance. For high correction values, it is worth choosing frames with a smaller lens area. Some lenses offer METS optimization - fitting the smallest required diameter. We recommend optimization for positive correction values.
Classic "spherical" lens construction.
Hi-Vision Longlife BlueControl **reduces the amount of blue light**
**Very easy to keep clean** thanks to dirt and dust repellent layers. The lens surface is **seven times harder** than standard HARD coating.
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.
