These glasses are fine, however they are not polarized.  I went to a Sunglass Hut at the mall today and they showed me a test where you look at a hologram with polarized glasses and you see colors.  The pair I received from Amazon, which were then listed as being polarized, show no colors.  They are not polarized.  The sales person at Sunglass Hut knew immediately that I had been duped.  I could have bought these in the polarized version for little more (10-15 dollars) and I would have had Amazon not fraudulently labeled these sunglasses as being polarized.  I thought I was getting a deal on polarized glasses, but was simply mislead into buying regular sunglasses for way more than I should have paid. Beware.
