How to Use Polarised Sunglasses: 

1. Wear Over Eyes: Place the sunglasses over your eyes, ensuring that both lenses cover your eyes completely. 
2. Storage: When not in use, store your sunglasses in a protective case to prevent scratches and damage to the lenses. This will also help maintain their quality and longevity. 
3. Maintenance: Regularly clean your sunglasses with a microfiber cloth to remove dust, fingerprints, and smudges. Avoid using harsh chemicals or abrasive materials that could damage the lenses.
