We provide triacetate(TAC) polarized, ISARC Polarized, and polycarbonate(PC) non-polarized lenses. We also provide high-end replacement lenses, it is our Mr. Shield lenses, it is injected molded polycarbonate polarized lenses.

ISARC means Inner Side Anti-Reflection Coating.Inner side of the lenses are coated by a blue anti-reflection layer, which can eliminate inner side flare caused from back light and provide better wearing experience.

Mr. Shield means Multiple Resistance Shield, which can resist corruption from sea/pool/soap water. Mr. Shield lenses are also taper corrected, which can provide better optics characteristics; Mr. Shield lenses are made from polycarbonate polarized material, which is harder than TAC, it means the lenses can tolerate more damages and scratches.
