Sleeping too little or too much, snoring, daytime sleepiness and insomnia may all increase the risk of glaucoma, a common eye condition that affects millions of people and can lead to blindness, according to a decade-long study.

It is well known that sleeping badly can affect judgment, mood, ability to learn and retain information, and may increase the risk of serious accidents and injury.
