Prada Gold-colored Before using your sunglasses, make sure they fit your face completely and comfortably; the nose and ear pieces should not press against your skin. Wear your sunglasses in sunlight to protect your eyes from UV rays. When cleaning the lenses, use only a microfiber cloth; paper towels or rough cloths may cause scratches. You can clean them with warm water and mild soap, avoiding harsh chemicals. When not in use, store your sunglasses in a hard case to protect them from scratches and impacts. Do not leave them in a hot car; this can cause deformation of the frame and lenses. Do not choose sunglasses without UV protection. Do not use them at night or in dimly lit environments. Replace your sunglasses instead of using scratched or damaged lenses.
