Setup, Compatibility & Care
To ensure your Coach Cr638 sunglasses remain in pristine condition, follow these care guidelines:
- Cleaning: Use a microfiber cloth and a mild lens cleaning solution to wipe away smudges. Avoid using paper towels or tissues, which can leave microscopic scratches on the lenses.
- Storage: Always store your sunglasses in a protective hard case when not in use to prevent frame deformation and lens surface damage.
- Handling: Remove the sunglasses using both hands to maintain the alignment of the arms and hinges.
- Maintenance: Periodically check the screws at the hinges to ensure they remain snug; if they become loose, use a precision optical screwdriver to tighten them gently.
