1. Anti-reflective protective lenses: These lenses are coated with a thin layer of magnesium fluoride to prevent glare from reflecting off the surface, allowing you to see more clearly and without interference from the glare.To check if your sunglasses really have anti-reflective protection, aim your glasses at a light source. If you see a purple or green reflection, it means the lenses are coated with anti-reflective coatings.
