Bausch & Lomb Sight Savers Lens Cloths.
These are ANCIENT. I think I had these with my first pair of glasses ever, which would have been in the 80’s. I can’t believe I actually kept them. They are dry and completely useless. I tried them this morning just to see if they work, and smudged the hell out of my lenses. All the cloth did was move around the grime and streak the lens. Not helpful. And I definitely wouldn’t trust these on a camera lens, so I have no further need to keep this pack.
