Let’s talk about some cosmetic issues first. Many experts suggest that there’s a correlation between lack of sleep and those dark circles or bags under your eyes. That’s because lack of sleep tends to increase the retention of blood and fluid around the eyes.
Sleepy eyes are often dry eyes. Your eyes need a constant supply of tears for optimum function, which is why blinking is so important. Insomnia prevents eyes from getting needed fluid circulation That fluid both cleans and renews the eyes-staying awake for an abnormal number of hours works against eye health.
Another and even odder consequence of sleep deprivation is eye spasms. Called myokymia, this involuntary eye twitching can be uncomfortable and distracting. Adequate sleep rests the body and all its eye muscles in turn, so the twitching should only be temporary. Even higher on the trouble scale might be popped eye vessels that can occur when a night’s rest just doesn’t come. Though they are usually not painful, the “bloodied eye” look is definitely not one most people cherish.
There are rarer eye conditions that are linked with sleep loss: one of those is Anterior Ischemic Optic Neuropathy (AION).
