Sunglasses have become an important part of life. For sunglasses, more people value the style of the sunglasses, but they know little about the material of the sunglasses. Since the effect of sunglasses lenses on the eyes cannot be ignored, we have more or less understanding of what materials are good for sunglasses. Let's take a look at what materials are good for sunglasses. Since the frames of sunglasses are also made of different materials, different frame materials have their own advantages in performance. Manganese-nickel alloy frames are mainly alloys with manganese and nickel as the main alloying elements. This material has good corrosion resistance, strong strength, and good safety. First, the TR-90 material is made of super-tough memory resin material imported from Switzerland as the first-class frame material. It has super flexibility, excellent anti-deformation performance, and light weight, which greatly reduces the weight of the glasses. Strong impact resistance, effective resistance to impact, good safety performance, is the material used in many sports glasses. Second, aluminum-magnesium alloy materials are widely used in high-tech products such as mobile phones and laptop computers. Aluminum-magnesium alloy frames are also used in sunglasses. The frames are not easy to break, have good impact resistance, good durability, and good gloss and texture. Third, titanium materials Titanium alloys are also widely used in frames. Beta titanium density structure is better than titanium metal, and it has good elasticity, light weight and high hardness. Fourth, epoxy resin is widely used to make temples and high-grade frames, etc. It has good temperature resistance, good elasticity, and also has memory function and high strength. For different performance requirements, the material of the frame is also different. If it is sports sunglasses, whether it is the lens or the frame, it is necessary to downgrade the material with higher safety. For those driving and activities that are affected by glare, it is necessary to choose lenses with polarized effects. Therefore, it is not possible to say which material is good. Each material has its own characteristics and meets the needs.
