Setup, Compatibility & Care
To ensure your Ray-Ban 3791 sunglasses last, adjust the nosepads gently by pressing them closer together or wider apart until the frame sits securely on your nose without slipping. Since these are rimless, avoid placing them face-down on hard surfaces to prevent lens scratching. When cleaning, use only a microfiber cloth and a mild lens cleaning solution; avoid using paper towels or abrasive fabrics. Store them in the provided protective case when not in use to protect the lens edges and metal structure from accidental pressure or bending.
