When a university professor friend of mine needs to write a thesis, or has a lot of work to do, he suffers from red eyes, blurry vision and headaches, and he becomes oversensitive to light.
He thought the symptoms were due to stress and working late at night, thinking this made his eyes tired. He believed the problems would subside after a good night's sleep.
