Tips
1-Never clean your polarized sunglasses with paper towels or clothing, which can leave scratches.  Just use clean water and Heptagram's included cloth to clean it. 
2-Never leave your sunglasses under car's front window, especially in summer.  Prolonged exposure to the oven-like temperatures inside a car can degrade the lens.
