PC color-changing lenses produced in Taiwan are used. PC color-changing lenses fill the shortcomings of traditional CR39 color-changing lenses and polarized color-changing lenses. 1. The shortcomings of CR39 color-changing lens: fragile, the speed of changing the belt is more than 15 seconds. 2. Disadvantages of polarized color lenses: the transparency can only reach lens No. 1 (43-80%), and the transparency is not enough for luminous use. In comparison, the transparency of PC polarized lenses can reach Europe No. 0 (transparency above 95%); the depth of discoloration can reach No. 0-3 (the discoloration speed is less than 0.5 seconds); in addition, the toughness and impact resistance of PC lenses are stronger. Advantages: high toughness, impact resistance, fast discoloration speed and high transparency.
