1.710 Aspherical SILKEN LASER-THIN is the new material in index 1.710 with an aspherical and super thin design.
It ranks between the already existing indexes 1,670 and 1,740, combining the best characteristics of both: versatility, efficiency, economy and aesthetic performance.
1.710 LASER-THIN lenses are made with aspherical geometry in order to guarantee minimum thicknesses even in high diopters (45% less than the normal CR39 1.50). Like the 1,740 lenses, the high refractive index guarantees the best aesthetic result compared to other lower indices, while maintaining excellent flexibility of use like the 1,670 index lenses.
Finally, the 1,710 LASER-THIN lenses offer the most advanced standard protective standards, guaranteeing total UV absorption in combination with the best coating. In this way will be reduce reflections, grease and dirt deposits and will be increase resistance to abrasions.
