A perfect spheric & aspheric design without any distortion, ST Hammer series are thinner and lighter! MR-7 is a Great material for thinner lenses with strong impact resistance. The MR-7 material is at the forefront of modern lens technology, it is lightweight and a further 15% thinner than a 1.60 index.
Our 1.67 MR-7 comes in HC, HCT, HMC (AR) , Super Hydrophobic (Super AR) & Primer coating.
What is MR Lenses? (MR-8, MR-7, MR-10, MR-174)
Excellent optical materials with high refractive index, high Abbe number, low specific gravity and high impact resistance are provided by polymerizing monomers of MR™ Series. MR™ Series is especially suitable for ophthalmic lenses and is known as the first thiourethane based high index lens material. MR™ Series offers a variety of products to provide the best solution for optical lens users.
