sunglasses recommendation guide: What are polarized sunglasses

　　On a sunny day, sunglasses become a must-have item to protect your eyes. However, how to choose the right sunglasses, especially polarized sunglasses? This guide will answer the questions for you.

　　First and foremost, it's crucial to understand the characteristics of polarized sunglasses. Polarized sunglasses effectively reduce glare and protect the eyes from glare by eliminating scattered light. In addition, they filter harmful rays, resist scratches and impacts, and provide comprehensive eye protection.

　　Next, focus on the choice of frame and lens. Frames are not only about supporting the lenses, but also about comfort and aesthetics. Different face shapes are suitable for different frame shapes, such as square frames for round faces, almost all frames for oval faces, and larger mirror styles are recommended for rectangular faces. In terms of frame materials, plastic, metal, and natural frames have their own advantages and disadvantages, so you can choose according to your personal needs and budget.

　　Lens material is the key to choosing sunglasses, and the common ones are glass, PC, resin, nylon, and TAC. Each material has its own characteristics in terms of optical properties, UV protection, weight and abrasion resistance. Among them, TAC lenses are widely used in polarized lenses, which have the advantages of corrosion resistance and light thinness, but have weak wear resistance.
