High definition Trivex Lenses Online - 1.61 MR-8 FSV High Index HMC optical lenses – Boris

Production Details

MR-8 is the standard high index lens material. Compared with lens materials of the same refractive index, due to the outstandingly high Abbe Value, dispersion is less likely to occur at the periphery of the field of view, and in particular, it has a balance of impact resistance and heat resistance.

The refractive index of MR-8 material is 1.60, the Abbe Value is 41, and the thermal deformation temperature is 118℃. It has high refractive index and high Abbe number, and has excellent impact resistance and static pressure load resistance. Provides great protection in terms of safety performance.

Production Introduction

In the long exploration since the birth of glasses, human beings have gone through a profound and arduous journey in the exploration of suitable lens materials, from amber, crystal to today’s MR materials.

From the classification of resin lens materials, there are mainly ADC materials (1.50 refractive index), DAP materials (1.56 refractive index), PC materials (1.59 refractive index), acrylic materials (1.60 refractive index), and high-refractive MR series.

In 1987, Mitsui Chemicals launched a polyurethane-based high-refractive-index lens material named MR-6. After continuous improvement, MR-8 material and other high-refractive MR series materials were subsequently developed.

MR-8 has a refractive index of 1.60 and an Abbe Value of 41. It has a high refractive index and a high Abbe number, and has excellent impact resistance and static pressure load resistance, providing great safety performance. Assure. In addition, its good flexibility and easy processing ability make the surface of MR-8 lens not easy to be broken when punching and cutting edges, even if the lens is dropped, it is not easy to break the edge. Ideal for cut-edge glasses. Lenses made of MR-8 material are not only lighter, thinner, stronger and more durable, but also surpassed the resin materials in the pre-MR era.

And MR-8 lens also has these advantages:

High index of refraction – improved aesthetics
High Abbe Number – Superior Visual Imaging Performance
Minimal internal stress – clear visual experience
Excellent impact resistance – improved safety performance
Excellent anti-static pressure performance – high safety performance
Better tensile strength – for more frames
Anti-aging – the lens is not easy to yellow
Excellent heat resistance – less prone to photometric shift
Excellent coating durability – lenses are more abrasion resistant
