Resin is a hydrocarbon (hydrocarbon) exudate from a variety of plants, especially conifers. Because of its special chemical structure and can be used as this latex paint and adhesive is valued. It’s a mixture of high molecular compounds, so it has different melting points. Resins can be divided into natural resins and synthetic resins. There are many kinds of resin, widely used in light industry and heavy industry, in daily life can also be seen, such as plastic, resin glasses, paint and so on. Resin lens is the lens after chemical processing and polishing with resin as raw material.
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. Coating is coating the lens with a layer of material that has different functions. some


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.
