Closing our eyes eliminates sensory stimuli like lights and movement so our bodies are more relaxed and able to slip into sleep. Also, if we slept with our eyes open all night, our eyes would be so dry they would be shriveled in just a few hours. So, closing of the eyelids is also protection for the eye during the sleep.

I close my eyes when I blink. But I don't sleep. I sit back and wait for others to sleep.

To prevent your eyes from drying out while you sleep. Otherwise, you will loose a lot of moisture, and you will damage your eyes and eventually you may become slightly dehydrated.

You close your eyes so you won't be distracted and won't have to work the part of your brain that controls sight. They stay closed because your muscles are at rest.

Relaxing

So the spiders dont crawl in my eyes

Yes.

Helps me not to look at the ugly **** face of my ex. There. I rest my case.

Me gusta.

To see the dreams I dream.

Why do you close yours?
