Hi Ashanti

I'm not sure, but I think it is because of a reflex Arc. A so called 
programmed response ... as long as you are awake ..there is a little 
program controlling your eye lids ..which tells them to blink each couple 
off seconds. When you close your eyes for a couple of minutes with the 
intention to go to sleep this program will be shut down and a new neuronal 
program will take care of your eyes. But if you just close your eyes to 
give them rest for a wile, the normal neuronal (awake eye's open) program 
will take care of your eye's, and that means blinking one's in a while.
