what do your eyes do when you sleep?

 

Your eyes roll slowly, opening and closing during stage 1 of sleep, when in deep sleep during stages 2-4 your eyes are still. There’s a stage of our sleep cycle called rapid eye movement (REM). During REM sleep, our eyeballs move rapidly behind our eyelids and our bodies become more still. It’s during this stage that we dream. It’s not known why our eyes move so much during this stage, but some believe it could be because we’re watching the scenes in our dreams.

When you don’t get enough sleep, your eyes can feel strained, dry and itch
y the next day. Lack of sleep can cause eye strain, burst blood vessels and dry eye.

Our eyes go through a lot during the day. After spending so many hours using your eyes, it's important for them to get enough recovery time when you're asleep. Getting enough sleep will give your eyes moisture throughout the night so that they can function properly when you wake up.

"The window to our soul" has been said about our eyes. It turns out that they're also a good indicator of our general health. Your eye doctor can view and analyse the health and condition of the blood vessels in your retina during a full eye exam, which are an excellent predictor of the health of blood vessels throughout your body. Changes in the appearance of the retinal blood supply and blood vessels are noticeable in conditions such as diabetes, hypertension, and hypercholesterolemia.  Anyone with diabetes or who may be at risk for the disease should have their eyes examined at least once a year due to obesity, family history or other reasons. Diabetic eye disease, the main cause of blindness in adults, affects more than 30 million Americans with diabetes and another 84 million who have prediabetes. Diabetic eye disease has no apparent symptoms in its early stages; only a comprehensive eye exam can discover indic ators of the disease early enough to avoid vision loss.
