A few months earlier, I started wearing a pair of my friend’s old glasses and my vision was excellent. After losing those, I went to the opthamologist and got a new prescription.

I had a set made with that new prescription, and my vision isn’t really almost as excellent as it was using the glasses that weren’t mine.
