Can hu­mans sleep with their eyes open?

Science Illustrated - - ASK US -

The eyes can be open dur­ing or­di­nary sleep, but the sleep­ing per­son is un­con­scious and can­not see any­thing. The cause is typ­i­cally that a nerve func­tion in the eye re­gion fails, mak­ing the eye­lids slide open. The con­di­tion can oc­cur tem­po­rar­ily in healthy peo­ple, and for un­known rea­sons, it is most com­mon among small chil­dren, who grow out of it. Sleep­ing with open eyes can also be a per­ma­nent con­di­tion among adults caused by blood clots in the brain or fa­cial paral­y­sis. The phe­nom­e­non does not harm the vis­ual or­gan, but the eyes can dry out from be­ing open all night.
