Setup, Compatibility & Care
To ensure your Shield Sunglasses maintain their clarity and structural integrity, proper maintenance is vital. Always store the glasses in the provided protective case when not in use to avoid scratches on the continuous lens surface. When cleaning, rinse the lenses with lukewarm water to remove abrasive particles like dust or sand before wiping with a microfiber cloth. Avoid using paper towels or clothing, as these can leave micro-scratches on the lens finish. If the frame feels loose after heavy use, check the hinge screws and ensure they are tightened with an appropriate precision screwdriver. Note that these sunglasses are designed for a standard adult fit; if they feel tight, allow the frame to rest to its natural shape rather than force-stretching the material.
