Children's sunglasses are designed to protect children's eyes from strong light or harmful ultraviolet rays. They are fashionable, beautiful, and radiation-proof. When buying children's sunglasses, you should choose lenses with gray or smoky colors, which cause the least color distortion and the best color sense. The lens material should be high-quality optical glass or polycarbonate, among which polycarbonate lenses are more impact-resistant. The frame should be made of sturdy TR90/PC or metal, and the ears tips, nosepads and temples should feel comfortable when worn.
