MR Lenses supplied by Younger Optics
MR™ SERIES - TRADEMARK OF SAFE, CLEAR AND LIGHTWEIGHT LENSES
The MR™ Series, created by Mitsui Chemicals provide optical lenses with a high refractive index, high Abbe numbers, low specific gravity and high impact resistance. The MR™ Series has good mechanical strength and stree free properties making it suitable for various unique lens designs such as rimless frames and high curve lenses. Marké Optical currently uses 1.60 MR-8 and 1.67 MR-10 supplied by Younger Optics.
MR-8
The best balanced high index lens material with the largest share of R.I. 1.60 lens material market.
MR-8 is suited to any strength opthalmic lens and is a new standard in ophthalmic lens material.
Optical clarity - providing optical performance similar to glass lenses, for clear vision with minimal chromatic abberations.
Thin and light - a high refractive index provides all day comfort and aesthetics through a light and thin lens.
Strong and durable - with an impact resistance rating comparable with polycarbonate, this lens provides enhanced safety and durability.
MR-10
MR-10 is the global standard R.I 1.67 lens material.
Great material for thinner lenses with strong impact resistance and higher heat distortion temperature.
Optical clarity - the MR-10 lens has been designed to be light and thin with an optical clarity similiar to polycarbonate and acrylic 1.60.
Thin and light - a high refractive index provides all day comfort and aesthetics through a light and thin lens.
Strong and durable - with an impact resistance rating comparable with polycarbonate, this lens provides enhanced safety and durability.
