Eye Glasses Method

1. If you have glasses take a bit of paper, write your notes on it, fold it up and put it in the hinge. When you need them take off your glasses and take the paper, unfold it, If the teacher ask what you're doing say your hinge has a gap and is 'Un-even' and you're adjusting the paper.
2. Then when done fold it back up put it back and continue.
3. Throw out the paper later on.
