Review of Easton Diamond Flare Sport Sunglasses

I bought 2 pairs of these.I am very gentle on sunglasses, using them only to golf and drive a car.I was cleaning the lens on one pair and the lens fell out!The lenses are 1-piece, and had cracked right at the nose piece section.I checked the other pair, which I have won maybe 3 times, and I find a crack in them also, but it is not all the way through.I intend to return the sunglasses for exchange; we'll see if they'll do this.
