Oakley Men's Industrial Sunglasses

safety glasses, nothing more and nothing less. Kind of heavy. They do a fair job of anti-fog but they don't seem any better than my ray bans or rx flaks that I normally wear. They WILL fog if you get hot enough. There is a double image from the lens if you look at a bright light that my other oakleys and... well... all other glasses... don't have.They are, however, a gazillion times better than the cheezy Smith & Wesson (Taiwan brand?) that we normally get for work. And they have the z87 stamp so all is well in that department.
