For what it's worth, now that they are able to place my prescription lenses in a small enough pair of Oakley's that's what I've been using and here's what they say

All Oakley eyewear are tested to meet ANSI high velocity and high impact standards. However, please note that not all are marked as certified ANSI Z87. Thus, while other Oakley styles may surpass these standards, we cannot endorse this particular style as industrial safety glasses as they are not marked for ANSI Z87 compliance. Should you require Z87 certified Oakley eyewear, please visit our Oakley Safety Glasses section.

Yes they are kind of expensive - but, needing prescription lenses and not being particularly enamored with the kind that clip your prescription in behind the actual lenses, most anything is pricey. I've got quarter jackets (made for kids) and I've been very, very satisfied with them. While they honestly don't look much different than most other wrap around sunglasses, they really do have some better engineering. They move air much better than other pairs I've used. It takes a lot to fog them up, but they still keep grit and air totally out of your eyes.
