Query: safety glasses w/mirror hard coat.

I bought these because I wanted affordable sunglasses that were wide enough for my head and would not scratch when they closed. When they arrived, (almost the same day!) I was surprised to see that they were safety glasses and had a mirrored lenses. I accepted it becaused they looked like normal glasses. I am very pleased and wear them daily here in the Hot GA sunshine. The hinges are loose and I can't tighten them which is a bummer. For the price I will manage, I just wish they had included shipping with the cost.
