Care Tips for TAC Lenses

Proper maintenance can extend the lifespan of your TAC lenses:

• Cleaning: Use a microfiber cloth to gently wipe the lenses. Avoid abrasive materials that can scratch the surface.
• Storage: Keep your sunglasses in a protective case when not in use to prevent scratches and impact damage.
