High-index monomers for premium optical lenses

Characteristic
  • Basic information

Overview

Premium optical lenses with high refractive index, high Abbe number, low specific gravity, and high impact resistance are made by polymerizing MR™ Series monomers. MR™ Series is especially suitable for ophthalmic lenses and known as the first thiourethane based high index lens material. MR™ Series offers various products to provide the best solution for optical lens wearers.

MR™ Series Features

MR™ Series clear resins obtained by heat-polymerization have the following features:

HIGH REFRACTIVE INDEX
  • Suitable for thinner & lighter lenses
SUPERB OPTICAL QUALITY
  • Both high refractive index and high Abbe number give optical performance similar to glass lenses
  • Glass mold-casted MR™ Series shows minimal stress-strain
MECHANICAL STRENGTH
  • Good impact and static load resistance contribute to ophthalmic lens wearer eye safety
DURABILITY & WEATHERABILITY
  • Good weatherability for minimal change in lens color after years of use
  • Good compatibility with various coating materials
PREMIUM OPHTHALMIC & SUNGLASS APPLICATIONS
  • Good mechanical strength for fashionable rim-less frames
  • Good color tintability for high fashion sunglasses which have special color needs
  • Suitable for various lens applications including photochromic & polarized lenses
