How do I choose sunglasses?

　　Choosing sunglasses isn't just for fashion, it's more important to protect your eyes from UV rays. Here are some tips to help you choose the right sunglasses for you:

　　Learn about lens material: The lens material of your sunglasses is directly related to their protection, durability and comfort. At present, the common lens materials on the market are mainly resin sheets and glass sheets. The resin sheet is lightweight, impact-resistant, and low-cost, making it suitable for daily wear; The glass sheet has good light transmittance and strong wear resistance, but it is relatively heavy, which is suitable for occasions with high requirements for clarity. In recent years, new materials such as nylon sheets and polarizers have also emerged, which have better protection performance in specific environments (such as outdoor sports, driving, etc.).

　　Choosing the right lens color: Lens color is not just chosen for aesthetic reasons, as different colors filter light differently, affecting visual comfort and contrast perception. The gray lens can evenly filter various wavelengths of light, maintaining the most realistic color perception, suitable for most environments; Brown lenses enhance contrast and make the scene more vivid, suitable for outdoor activities; Green lenses reduce glare, suitable for long hours of reading or computer work; Yellow lenses improve contrast and are suitable for low-light environments; Blue or mercury lenses are mainly used for decoration and have limited practical protection.
