1.61 MR-8 Blue Cut Single Vision HMC Optical lenses
1.60 means that the refractive index of the lens is 1.60, the higher the refractive index, the thinner the lens of the same degree.
MR-8 is a polyurethane resin lens.
1. Among all 1.60 lenses, its optical performance is relatively excellent, and the Abbe number can reach 42, which means that the clarity and fidelity of seeing things will be higher;
2. Its tensile strength can reach 80.5, which is better than ordinary lens materials;
3. Its heat resistance can reach 100℃, the performance is relatively stable, the proportion is also relatively low.
