These glasses have a good quality feel to them and they can take some punishment. Apparently I punished mine too much and caused one of the lenses to break or &#34;tear&#34;. I contacted the seller and they told me they'd send me a new one. I've received many compliments on the way they look while wearing them. I wear them at work mostly. I walk around all day in the hot intense sun inspecting above-ground gas pipelines. I recommend this product.
