Setup, Compatibility & Care
The Costa Finlet sunglasses arrive ready for immediate use. To ensure a long lifespan, store your glasses in a protective hard case when not in use to prevent scratching the lenses. To clean the lenses, rinse them with fresh water to remove any salt or debris, then wipe gently with a clean, dry microfiber cloth. Avoid using harsh household cleaners, paper towels, or clothing fabric, as these can strip protective coatings or cause micro-scratches. Check the hinges periodically to ensure they remain snug and functional; if they become loose, consult a professional eyewear technician for adjustment.
