Setup, Compatibility & Care
Because these frames are designed as a fixed-bridge style, no mechanical setup is required; however, you may visit an authorized optician if a custom adjustment to the temple tips is needed to ensure a secure fit. To maintain the lenses, use only a microfiber cloth and a mild lens cleaning solution to prevent micro-scratches. Avoid placing the sunglasses lens-side down on abrasive surfaces. When not in use, always store the PO 0091S in a hard-shell protective case to shield the frame from accidental pressure or impact. If the hinges feel loose after extended use, take them to a professional for a tension adjustment rather than attempting to tighten them with standard household tools.
