ages ago I bought pair from Italy for 150E, lost them few months later and was sick for a week. Then purchase 2 pairs from china for 5 E each lost one still have the other one and I can't tell the difference (except the price tag)
EDIT: can't PM but this was years ago. I tried to look on my email for tracks where I bought them but nothing came up.
I had Rayban Polaroid I got in specsavers. They are terrible for driving. I found the contrast under trees too much. Replaced them with Oakleys I got in Florida airport. Much better vision in all lights. Also got a free pair of extra lenses in a lighter tint.
