Depending on the craft, material, and polarization rate, the quality of the polarizer will vary greatly, and whether the lens has a polarizing effect, you can’t see it simply by simply checking it, and you need to use a certain method to identify it, so understand some to distinguish the polarizer. The method is necessary. 1. In the regular sunglasses, polarized sunglasses will have a clear electrostatic label of polarized lens material on the lens, or the product tag will indicate the use of polarized lens. 2. Generally, when buying sunglasses in professional eyeglass shops, there will be a polarized test piece for testing. Part of the pattern on the test piece cannot be recognized by the naked eye, but it can be clearly seen through the polarized lens.

1. AC lens: low cost, brittle material, brittle chips may be cracked, and general optical index stability; 2. PC lens: The cost is a little higher than that of AC. It is a safety lens called "bullet-proof glass". In fact, there will be no brittle chips and cracks, and the optical index stability is also general; 3. CR39 lens: the cost is higher than the previous two, the optical index is stable, and the clarity is better; 4. Glass lens: high definition, excellent optical index, strong abrasion resistance, heavier weight, easy to be brittle; 5. Nylon lens: clarity is second only to glass lens, and other optical indicators are excellent.

In outdoor activities, especially plateau areas with strong ultraviolet rays, white ski resorts and places with dazzling light, many travellers use ski outdoor goggles to block the dazzling light to reduce fatigue caused by eye adjustment or strong light stimulation. hurt. So, what are the characteristics of different mirror colors of outdoor ski glasses or what are the differences between them? 1. The gray film belongs to the neutral color system, which can evenly absorb any color spectrum. Although the scene will become dark when viewed, there will be no obvious color difference, and it can show a real and natural feeling. Suitable for outdoor activities who like sightseeing and photography. 2. The blue-gray lens is similar to the gray lens and is also a neutral lens, but the color is slightly darker and the visible light absorption rate is higher. If the outdoor activities are particularly bright, you can consider wearing blue-gray eyes. 3. The surface of mercury lens adopts high-density mirror coating. Such lenses absorb and reflect more visible light, and are suitable for long-term outdoor sports.
