The only reason I did buy new glasses, even thou they had to be a few years old, was because while I was at work one day I had to pull frozen from the freezer. When I was done my glasses weren't de-fogging so I wiped the lenses on my apron cause I'm so blind without them, and the frame broke. The frames had already broke a few times now, but at this point, even after they were gorilla glued, I figured it was time to fork over money for a new pair.
Gahhhh I hate that! I'm pretty blind too, so sorry that happened. And at work too!
