I'm looking for a good set of goggles that I can wear over standard glasses. Something I can use in the shop and driving down dusty roads on the way to the trail. Here is what I need: 1) Must fit over glasses. 2) Must be safety lenses. 3) Must seal fairly well (dusty drives) 4) Must be VERY comfortable so I don't want to take them off in the shop. 5) Must be vented (without letting dust in). Here is what I would like: 1) Replaceable lenses (may get scratched, overspray, etc.) 2) Quick change dark lense for plasma? 3) Not too expensive. /forums/images/graemlins/laugh.gif 4) UV Protection? Any suggestions on what to get or other things to look for?
