My first pair cost me $ 150.00. Up until then I was wearing the $ 5.00 to $:25.00 sun glasses. What a difference ! When I saw these I thought for sure they were knock offs. Nope not the case. I really over paid on my first pair and every bit as good as the 150.00 pair. I wish that I had bought 2 pair at the time. At the original $ 150.00 price I'd never wear these to the beach with salt water but at what I paid now sure why not
