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.
Standard "white" spectacle lenses without colored sun filters.
Standard HARD hardening. The most affordable lenses without coatings.
High-quality lenses at the best price.
Standard lenses with no comfort-enhancing coatings. Most affordable.
Standard optical material is characterized by good mechanical strength.
Without special filters, maximum clarity and faithful color reproduction.
