Monofocal Lens High Index

High index 1.61/1.67/1.71/1.74

High index lenses are thinner and lighter options if you require significant visual correction in your glasses, providing you with greater comfort and aesthetics. The choice of index will depend on the recommendation of an eye care professional and your individual needs.

Power Range

MR™ for Premium Global Standard Lenses

Polymerized MR series monomers are excellent optical materials with high refractive index, high ABBE index, low specific density and high impact resistance. The MR series is especially suitable for ophthalmic lenses and is known as the first polyurethane-based high index lens material.
