1.710 Aspheric SILKEN LASER-THIN is our new material with a refractive index of 1.710 and super-thin, aspheric design. Falling between our 1.670 and 1.740 index lenses, it unites the best
of both worlds in terms of versatility, efficiency, cost, and aesthetics.
Our 1.710 LASER-THIN lenses feature an aspheric geometry in order to ensure minimal thickness even at higher prescription strengths (45% thinner than a standard 1.50 CR-39). On a par with
our 1.740 lenses, the high refractive index ensures superior aesthetics compared to lower indexes while maintaining the excellent versatility of 1.670-index lenses.
