This item has been around for years under the name "Rollens". As I recall, they are just a little too tall to fit into a 35mm film case.

These prices are per bags of 100: http://www.sigmapharmaceuticals.com/Prod...CFQgtawodaVcTLw

That's exactly what I thought when I saw the OP. I always keep an extra pair of glasses in my winter pack and usually end up never using them but frequently breaking them (I use really cheap ones that I don't care about and keep them in a semi-rigid case). These roll up ones should work great as an emergency backup - a lot better than duct tape or tree bark.

Thanks for the tip!

I EDC polarized shaded sunglasses all year long. These would make a decent back up I suppose. I really don't think they'll help my looks much, though. What could you do to make Cousin Eddy look better?

I've been trying to find something like that for my urban kit, but with clear plastic, not tinted. If I'm ever in any kind of collapse and lose my glasses, something like that could come in handy to keep debris out of my eyes, especially if I end up underground. I've looked at goggles (limited vision and bulky) and assorted other things, but to no avail.

You mean like this ?

Yes, T_Co, but foldable. That one is rigid. I've experimented with plastic wrap--something to tie around the eyes. Kirkland brand is pretty clear--other brands aren't.

Or these and use an elastic band instead of the frames.

T-Co--I'll have to "see" (hmmm) how that 2-piece works. I carry a big rubber band in my kit that fits around my head. Can use it as a headband to attach a Photon clip, stick the cellophane under it for glasses, hold down emergency poncho hood. I'm always amazed at how useful these inexpensive, genius-inspired items (rubber bands, paper clips, safety pins, etc) are.

I think I'll try to cut a clear plastic table cloth or some other plastic--something I can roll up and fit in my EDC.

The link below are to some fold-flat sunglasses that I picked up once at a MOMA store for $12.

They are a bit costlier but they fold totally flat and come in a rigid case. I keep them as back up shades in my Jeep's emergency kit.

The drawback to them is because they fold flat, they don't bend around your face and leave large un-protected gaps on the sides.
