I've had prescription safety glasses, but they look and act pretty much like ordinary glasses. They just use polycarbonate for the lense and have a slightly beefier frame with clip-on side shields. Seems like you could use the side shields on any glasses and get the same level of dust protection. They do look dorky, if that's a problem. Come to think of it, you could probably make something out of leather or fabric that you tape or glue to your glass frames. Really you just want to keep the wind from blowing dust directly into your eyes. You don't need a complete seal or hard protection you'd get from safety goggles.Those are two things I will definitely NOT neglect to bring. Does anybody here have experience with presricption sunglasses and/or goggles? I don't know how I feel about bringing my glasses to the desert and I can't wear contacts ( I mean they can't make my script in contact-form), so if it's not ludicrously expensive (very likely) I might get some script goggles/sunglasses.
For sunglasses, what do you normally do?
You can get goggles made to fit around regular glasses. There are a number of different types available.
