You need to sleep enough - for your eyes only if that.

The lack of sleep is the ongoing problem of the generation. It can can hurt your eyes. Here are the problems starting with the least serious and progressing: Eye spasms Your eyes twitch and the annoying twitching that just won't go away? It's called myokymia, and on the surface, it's nothing to worry about. But pay attention to that twitch, because it's a sign you need more sleep. More importantly, it very well could be a sign of more serious developing issues. Dry eye Depending on the climate and time of year, the air in your house is probably too dry. Too little sleep means your eyes aren't closed enough, so they're not getting the tears and lubrication they need. Possible effects include pain, light sensitivity, itching, redness, or even blurred vision. Bloodshot eyes Without enough time to recover from the day's eye strain, blood vessels in your eyes can swell and burst. So that's where your kids get that "I've been studying all night" look. Now a pair of quite serious conditions Ischemic Optic Neuropathy Chronic strain on the eye's blood vessels, which is a frequent side effect of sleep deprivation, can cause a blockage that's sometimes called a "stroke at the back of the eye." With blood flow to the optic nerve blocked, you can lose some or all of the vision in your eye. Glaucoma People with Obstructive Sleep Apnea had a 67% greater chance of developing glaucoma. Glaucoma, if not detected early enough, will cost you your vision. Sleep deprivation alone doesn't cause glaucoma, but if you or someone in your family has sleep apnea, regular eye exams are essential. So please, do your eyes a favor, start going to bed close an hour earlier.
