Why does we rub our eyes when we are tired?
In: Biology
Dry Eye Guy is right to some extend. When your eyelids appear to be heavy you would also get the feeling that foreign particles could be in or around your eyelids, causing you to “rub it out”… When you’re sleeping, your eyes continue to manufacture tears and mucus. But since you’re not blinking, the excess matter gathers in the corners of your eyes and in your eyelashes. So you tend to rub your eyes in the morning.
