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.
Super Hi-Vision is an anti-reflective coating providing excellent 99.9% clarity. It features integrated layers improving surface durability - they are three times more scratch-resistant. Thanks to the anti-water and dirt-repellent layer, water leaves no smudges on the lens, and they stay clean longer and are easier to care for.
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.
Standard optical material is characterized by good mechanical strength.
Without special filters, maximum clarity and faithful color reproduction.
