Setup, Compatibility & Care
To ensure your DG4431 sunglasses remain in pristine condition, always store them in a hard-shell case when not in use. Avoid leaving them on the dashboard of a vehicle where extreme heat can warp frame material over time. To clean, rinse the lenses under lukewarm water to remove abrasive particles, then wipe gently with a clean microfiber cloth. Never use harsh household chemicals or paper-based products, as these can strip lens coatings or scratch the transparent frame surface. Adjustments for fit should be performed by a professional optician to avoid stressing the frame hinges.
