I knocked my glasses off at work last week. The frames broke on the cement floor of the warehouse. The one lens that fell out was not scratched, and I taped it back in temporarily. Over the weekend I glued the broken frame together. It wasn’t a perfect job; the lens was loose so I cut a piece of rubber band to fill up the space. I colored over the rubber band and the dried glue with a black permanent marker, and the repair isn’t noticeable without a close look.
