I'd suggest looking at
http://www.uvex.us/uvex.aspx
They have a category called Goggles, in the Product Selector, you can select Dust as one of your options.
One word of thoughtness, I'd stand near a fan before taking them off. I recently was doing sanding with some goggles, took them off and poof, a small cloud of dust.....
I have a new pair of Ultra-spec 2001 OTG (Over-the-Glass) safety glasses from them that I love.
