When choosing sunglasses, it is important to ensure that they can block both UVA and UVB radiation. This is the most important factor in choosing sunglasses. It is best to choose impact resistant lens materials, such as polycarbonate, which is particularly important for sports activities or occasions where glasses are prone to injury. If you frequently drive or engage in water activities, a pair of polarized sunglasses can effectively reduce reflection and provide clearer visibility.

Gently wipe the lenses with a specialized eyeglass cloth, avoiding using clothing or tissues as they may contain hard particles that can scratch the lenses= Prolonged exposure of glasses to high temperatures, especially inside the car, may cause deformation of the lenses and frames. When not in use, glasses should be stored in a hard glasses case to avoid being scratched or broken.

Regularly check if the screws of the lenses and frames are loose, and tighten or replace them if necessary. In addition, cosmetics, sunscreen, and hair spray products may cause damage to the frame and lenses, and direct contact should be avoided.
