The following is an overview of the protection function of the snow glasses on the glasses from the light processing technology of different lenses. The concentration principle is different, but the goal is the same, and of course the effect is different.
1) UV, it is derived from ultraviolet, ultraviolet rays, but of course the anti-ultraviolet effect of each brand is different, and the resin material is also different, this can be seen by the price.
2) AR, derived from anti-reflect. 3) AR, the word is much stranger, it comes from anti-reflect,
4) Polarized, the original meaning is polarized light, the principle of polarized light should be understood by those who have played photography or have a better physics in middle school, and those who don’t understand the principle can just ask friends around to understand it. Basically, it’s like chaos. When the wind blows over a fence, the wind will naturally weaken, and the direction of the wind will basically stabilize. Generally, polarized lenses of different colors have different properties.
Take the different properties of different colors of AXE polarized lenses as an example:
·Gray, keep the natural color, suitable for sunny days and strong sunlight. Visible light perspective rate 20%; polarized light 99%
·Yellow, suitable for use in the morning, evening, cloudy or dark water. Visible light perspective rate 40%; polarized light 95%
·Gray-green, keep the comfort of the glasses in strong light. Visible light perspective rate 25%; polarized light 98%
·Brown, because of the strong contrast, use it in the morning, evening, cloudy or insufficient light to ensure a clear vision. Visible light perspective rate 30%; polarized light 95%
·Silver, used in strong sunlight, can reduce the dazzling degree of light or reflection in snow. Visible light see-through rate 15%; polarized light 98%
·In the state of red and insufficient light, adjust the vividness of the warm color series to the naked eye. Visible light perspective rate 24%; polarized light 95%
5) Bright coating, which is also a technology to protect against glare. This process can reduce the glare through the principle of mirror reflection. Bright coating makes ski goggles more fashionable and the coating can block ultraviolet rays.
6) Transition color, this is actually nothing special. Its principle is the same as the transition color of sunglasses. Because most of the sun's rays are shining from above, the upper color of this kind of lens is heavier, and the downward transition is getting lighter and lighter. The principle is nothing. Particular, but the aesthetic effect is amazing, ha ha ha, I believe that the transitional color design in the sunglasses is also for aesthetic considerations. The technical content of the frame also determines the performance, quality, beauty, and grade of the entire pair of snow goggles... Most of the snow goggles' frames are matched with the lenses to play a protective and beautiful role, and there are usually ventilation holes.
The hardness of the frame must meet the design requirements. The frame of the first-line brand snow mirror uses TPU with a hardness of 85 or 90. This material has good impact resistance and is not easy to deform when the frame is injection molded.
The design of the ventilation holes, but this is not easy to test, because each type of snow goggles is designed for different levels of skiers. For example, for snow goggles suitable for beginners, the wind holes will be too large, then In the case of low speed, it can ensure better ventilation effect, and can quickly exhaust the steam from the eyes, thus having the effect of anti-fogging. Then this kind of snow goggles will have a lot of wind blowing into the snow goggles in the state of high-speed sliding, which will cause the glasses to cry, which will not have the expected effect.
