Setup, Compatibility & Care
Proper care is essential to maintaining the integrity of your Saint Laurent eyewear. When not in use, always store the SL 637 in its provided hard case to prevent the metal frame from warping or being crushed in a bag.
To clean the lenses and frame, use only a specialized microfiber cloth. Avoid using paper towels or abrasive household cleaning agents, which can strip the glossy finish or scratch the delicate metal coating. If the glasses feel loose, it is recommended to visit an authorized optician rather than attempting to bend the metal yourself, as improper pressure can cause the hinges to weaken.
