I love companies with value to support our planet and always happy to buy their products. My previous sunglasses was from oceancleanup when they were sending them for donation, the quality of those were not that great but I was very proud to wear them. I was very happy to find out about sea2see, and when I received my new sunglasses, I was shocked how good they are. I almost could not believe that glass can be that transparent with 0 reflection, 0 distortion, the frame also is so thin and light. They perform very well in strong sun. Supper happy about my purchase. The glasses are a bit on a pricy side, but it 100% worth it.
