The MR-174 is the star of the MR series family, with the highest refractive index in the series, making it the ultimate thin and light lens.
The MR-174 material has a refractive index of 1.74, an Abbe Value of 32, and a heat distortion temperature of 78°C. While achieving extreme lightness and thinness, it also uses “Do Green” products derived from plant materials.
MR-174 is a representative high-refractive index product in the global lens market. Therefore, consumers with higher degrees, or consumers who pursue the thin and light performance of lenses and are very concerned about environmental protection, widely buy MR. Lenses made of -174 material.
Production Introduction
Comparison of 1.74 and 1.67:
1.67 and 1.74 both represent the refractive index of the lens, and the specific difference is in the following four aspects.
1. Thickness
The higher the index of refraction of the material, the stronger the ability to refract incident light. The higher the refractive index, the thinner the thickness of the lens, that is, the thickness of the center of the lens is the same, the same degree of the same material, the edge of the lens with high refractive index is thinner than the edge of the lens with low refractive index.
That is to say, in the case of the same degree, a lens with a refractive index of 1.74 is thinner than a lens with a refractive index of 1.67.
2. Weight
Higher refractive index, thinner lenses, and lighter lenses for a more comfortable wearing experience.
That is to say, in the case of the same degree, a lens with a refractive index of 1.74 is lighter than a lens with a refractive index of 1.67.
3. Abbe Value (dispersion coefficient)
Generally speaking, the higher the refractive index of the lens, the more obvious the rainbow pattern on the edge when looking at things. This is the dispersion phenomenon of the lens, which is generally expressed by the Abbe Value (dispersion coefficient). The higher the Abbe Value , the better. The minimum Abbe Value of lenses for human wearing cannot be lower than 30.
