Steampunk?

These non-fog not-really-welding goggles are just what you need to cap off your costume. Sure, the flip-up dark lenses are too dark to see through easily (that's why they have conventional clear plastic lenses underneath them), but leaving them flipped up just adds to your zany, adventurous, steampunk persona. Aesthetics include side vents and an adjustable elastic head strap. And the goggles accept standard 50mm replacement lenses, but if you think the party is going to be that rough, we suggest that it would be cheaper and easier to just buy a couple of pairs at this price-from-the-past.
