I ordered more than once from this site & being a Michigander I like to keep my business local by buying local. Well anyway my safety glasses that I always purchase from you guys which are the indoor/outdoor with the 2.75 magnification. I wear these at my place of employment & I'm very careful with them not to scratch the lenses by always using foaming soap & water to clean them with. Well I'll tell you what I think they should last a little longer than a few days. I would really like to use them more than 1 week then have to dispose of them, especially when I'm flipping the bill because my employer refuses to carry these due to my medical condition. If you could have these same exact ones but made in the U.S.A. I'd probably buy them because then I'd know I'd be buying quality products.
