Production Introduction

1.56 is the refractive index of the lens

The higher the refractive index of the lens, the thinner the lens of the same degree. Most people use lenses with a refractive index of 1.56. If the degree is too high, the lenses with a refractive index of 1.56 will be very thick, so we should choose lenses with a larger refractive index.

Anti-ultraviolet film, some can play the effect of increasing the transmittance of the lens, is more clear glasses.

Generally, when selecting lenses, it is recommended that the refractive index should not be too high or too low, because lenses with inappropriate refractive index will increase the burden on patients’ eyes. Lenses with 1.56 have low refractive index, which is generally suitable for patients with low myopia or moderate myopia. It is generally recommended that people with moderate and low myopia choose lenses with refractive index between 1.50 and 1.60.

Refractive index is related to the thin thickness of the lens, but when selecting the lens, you should not only look at the refractive index, but also compare the specific gravity of the lens, light transmittance, UV resistance and other factors for comprehensive consideration.
