1.67 Blue cut Spin Photochromic Gray HMC Optical lenses

Short Description:

good lens, material is the key

The material of a pair of lenses plays a decisive role in their transmittance, durability and Abbe number (the rainbow pattern on the surface of the lens). It can carry out in-depth research and development on materials, with controllable quality and excellent performance.

film layer, make the lens easy to wear

Good lens film layer can give the lens more excellent performance, not only the optical performance such as transmittance has been greatly improved, its hardness, wear resistance, durability will be greatly improved.

In order to obtain some new and original excellent properties, the surface of the lens is coated with a certain thickness of single or multi-layer optical film by physical and chemical methods.

Strengthening film: also called added dura film, is a layer of metal oxide and coupling agent mixed with the refractive index of the lens. It has high hardness, high adhesion, high light transmission and other characteristics, can effectively improve the wear resistance of the lens, not easy to peel off and yellowing, greatly improve the service life of the lens.

Blue blocking glasses are glasses that prevent blue light from irritating your eyes. Special anti-blue light glasses can effectively isolate ultraviolet and radiation and can filter blue light, suitable for computer or TV mobile phone use.

Production Introduction

When choosing color-changing glasses, the functional characteristics of the lens, the use of the glasses, personal requirements for color and other aspects should be considered. Photochromic lenses can also be made into a variety of colors, such as gray, brown and so on.

Grey lenses: absorb infrared and 98% ultraviolet light. The biggest advantage of grey lens is that the original color of the scene will not be changed by the lens, and the biggest satisfaction is that it can effectively reduce the light intensity. Grey lens can absorb any color spectrum evenly, so the scenery will only be dark, but there is no obvious color difference, showing the true natural feeling. Belongs to the neutral color, in line with the use of all people.
