Sunglasses frames are made of premium plastic which is strong, flexible and lightweight. The lenses are made of polycarbonate (heat-resistant, ultra-lightweight and super impact-resistant), which means your sunglasses can be used for a long time without scratching or breaking. The sunglasses protect your eyes from UV rays and the premium lenses give you a natural and clear view, durable and unbreakable. Polarized sunglasses block reflected light, scattered light and strong direct light through multi-layer lenses to reduce eye fatigue and glare, restore true colours and provide you with maximum comfort and visibility for a more "natural" vision. The sunglasses feature precision-cut, scratch-resistant glass lenses that improve visual clarity and help reduce eye fatigue during outdoor activities. Sunglasses are suitable for a wide range of occasions, perfect for outdoor sports and activities such as walking, cycling, driving, shopping, travelling, hiking, and are suitable as a fashion accessory and daily wear all year round.
