High Index 1.60 MR-8 Spheric / Aspheric

About The Product

perfect Spheric / Aspheric design without any distortion, ST Hammer series lenses are thinner and lighter! Sometimes you really need to hit the nail on the head, wow and move your clients with ST Hammer lenses.
Compared to the standard 1.60, Mitsui series MR-8 material is easier to drill and absorbs tints more effectively. We recommend this material for rimless glazing; The MR-8 is simply the best balanced high index lens material in the market.

Both high refractive index and high Abbe number provide optical performance similar to glass lenses.

Enhanced Vision Quality: Available in Aspheric as well. Our 1.60 MR-8 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.
