We added the very best polarized UV400 lenses with mirror effect for these 100% fishing nets sunnies. We had to go to Italy to find a company that could help us produce high quality sunglasses using high-end polarized UV400 lenses. Because of the recycled plastic all frames have a nice marbeling effect and no two frames are the same, making every pair truly unique.When you buy these bad boys you cover our cost of cleaning 1,5 KM beach in Sri Lanka.
