·Both high refractive index and high Abbe number provide optical performance similar to glass lenses.
·High Abbe number material such as MR-8 minimizes the prism effect (chromatic aberration) of lenses and provides comfortable use for all wearers.
MR-8 resin is uniformly polymerized in a glass mold. Compared to injection molded polycarbonate lenses,
MR-8 resin lenses show minimal stress strain and offer stress free clear vision.
