Women 2. How to Use Use outdoors in sunny weather. Before putting on the glasses, make sure the lenses are clean and free of scratches. Put on and take off the glasses slowly, holding both arms, not with sudden movements. Do not keep the glasses on your head for long periods of time; this may cause the arms to loosen. 3. Cleaning and Maintenance Use a microfiber cloth to clean the glasses. If necessary, you can wash them gently with warm water and neutral soap. Do not use chemical cleaners, alcohol, detergent, or perfume, as these may damage the lens coating. After cleaning, dry the glasses with a soft cloth. 4. Storage Conditions When not in use, store your glasses in their protective case. Do not expose the glasses to high temperatures, humidity, or direct sunlight for long periods of time. To prevent scratches, make sure the lenses do not touch each other or hard surfaces. Sunglasses
