Setup, Compatibility & Care
To ensure your Ralph RA4150 sunglasses remain in excellent condition, always store them in a protective hard-shell case when not in use. Clean the lenses using a microfiber cloth and a dedicated optical cleaning solution, avoiding abrasive materials like paper towels or clothing, which can cause micro-scratches on the lens coatings. To maintain the frame, gently wipe the gold finish with a soft, dry cloth after exposure to salt or sweat to prevent oxidation. If the fit feels loose, take them to a professional optician for a gentle adjustment of the temple arms rather than attempting to bend them manually.
