Setup, Compatibility & Care
These sunglasses require no setup; simply adjust the frame temple arms if they feel too loose or tight behind the ears. To ensure the longevity of your DL2009U frames, follow these maintenance tips: Always store them in a protective hard case when not in use to prevent scratching. Clean the lenses using only a microfiber cloth and a dedicated lens cleaning solution; avoid using household paper towels or napkins as they can contain wood fibers that cause micro-scratches on the lens coating. If the frames become soiled, wash them gently with lukewarm water and a drop of mild, lotion-free soap, then dry thoroughly.
