Anyone use Safevision glasses?

I'd really like to get ahold of some reasonably priced prescription shooting glasses. These guys seem pretty good. But surfing around, I can't find any reviews on them. And it's a little weird to find a company like this that still works through mail order (??).

Anyways, any recommendations or reviews here?

Thanks!
