Enhanced generation 3 designs utilize lens blanks manufactured using “Variable Front Curve Technology” (VFCT). These special VFCT lens blanks offer a continuously increasing base curve on the front surface from top to bottom, providing a lower diopter in the distance zone and higher diopter in the reading zone. The state-of-art digital back-surface design is calculated in mutual accord with the unique variable base curve changes on the front surface. When the unique variable base curve front surface is combined with a sophisticated back-side digital design, both surfaces work together to produce a design that provides ideal base curves for very lens power. When embedded with the individual personalization parameters, the result is a finished lens that is comprehensively customized for each individual lens.
