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.
