Did you wear a pair all the time so that you can find the other pairs that you left lying around?Where do you put your glasses when you are not wearing them?
At school, I have to move around between classes, so I can't put them down in the same place.
At home, I started off with a pair by the phone, which escalated to a pair next the bed, a pair by the computer, a pair in my bag etc. Now I need them for all close work, including meal as I don't like eating blurred food.
