BTW, I wanted to add that the vintage safety glass I bought recentely, have metal mesh around the outer and bottom portion of the glasses, that fold when they're closed up. This metal mesh actually seems to protect the exposed area of glasses, making them somewhat more akin to goggles.
I wonder why safety glasses are not made like that today? At least I haven't seen them like that and most I see are like modern style rayban or similar fashion glasses, or big ugly square plastic goggles (I have a pair of those also, but they fog easy as I sweat). Those will at least protect pieces of metal from entering the eye as they seal on the face.
The vintage safety glasses are quite cool, IMO, not only as far as functionality but looks also. Of course, I tend to like old things, so not surprising I would like them.
