Please use a special glasses cloth to clean the lens. Pay attention to pinch the bridge of the nose, do not move too large, so as not to damage the frame. When the lens is stained with dust or other impurities, please rinse with running water before wiping. Dry rubbing is easy to scratch the lens. If cosmetics or other stains containing chemical solvents are attached to the lenses, please clean them with clean water as soon as possible to avoid corroding the lenses and coating.
Special note: glasses with polarized lenses should not be cleaned with ultrasound, otherwise the polarized effect will be destroyed. Sunglasses with diamond or other decorative frames are also not suitable for ultrasonic cleaning.
