Here are some materials of sports sunglasses suitable for running

Lens Materials

• Polycarbonate (PC) lenses: They have excellent impact resistance, being highly safe and not prone to breakage, which can effectively protect the eyes from accidental injuries during running. Meanwhile, they are very thin and light, comfortable to wear, and have good UV - protection capabilities, blocking 100% of ultraviolet rays. However, the surface of PC lenses is relatively easy to get scratched, so daily maintenance is required.

• Triacetate Cellulose (TAC) lenses: Usually used to make polarized lenses, they have good optical properties, high transparency, can provide a clear vision, and are also relatively light in weight with strong impact resistance, being one of the ideal choices for sports enthusiasts. Nevertheless, their surface hardness is low, their wear - resistance is poor, and their optical performance may be unstable in high - temperature or high - humidity environments.

• Nylon lenses: They have excellent optical properties, high clarity, and color fidelity. Nylon lenses are elastic and can be made into different shapes to better fit the face and reduce wind resistance. They are also suitable for wearing in sports occasions. However, nylon lenses have poor wear - resistance, are prone to deformation at high temperatures, and have a high production cost, so the price is relatively expensive.

  
  

  
  

  
  

Frame Materials

• TR - 90 material: This is a super - tough resin material with a smooth surface, good flexibility, and light weight, which is very comfortable to wear. It has the characteristics of high - temperature resistance, being able to withstand 350 - degree high temperatures instantaneously, and is not easy to melt or burn. Its impact resistance is more than twice that of cellulose acetate plastic (CA). It also has a memory function, and its anti - deformation index reaches 620KG/CM². It can adapt to different head shapes and the shaking during running, and is not easy to deform.

• Nylon or carbon - fiber materials: They are also lightweight materials that can reduce the burden during running. They have good strength and stability, are not easy to break, and can be designed into various fashionable styles to meet different people's aesthetic needs.
