honestly this, I only wear my glasses when absolutely needed
I used to do that, but got so fed up of having to stop and take my glasses out and put them on in class at school, and take them off again.
And it's all the more awkward when you're out and about and need to stop to put them on.
So I wear mine all the time now.
I can go without wearing them, but I feel funny without them on, on account of habit.
I'll periodically try to push them back up my nose even though they're not there.
