Why do I keep blinking when my eyes are closed?

The eye produces tears to lubricate the eyeball at all times. Blinking just washes the surface a little better I think. Your eyeballs are still lubricated while you are sleeping even thought the lids are closed. During REM (rapid eye movement) sleep, the eyeball moves under the lid and tears keep this movement fluid.

There are multiple muscles that control reflexes of blinking. The main muscles, in the upper eyelid, that control the opening and closing are the orbicularis oculi and levator palpebrae superioris muscle. The orbicularis oculi closes the eye, while the contraction of the levator palpebrae muscle opens the eye.

Excessive blinking can be caused by problems with the eyelids or anterior segment (front surface of the eye), habitual tics, refractive error (need for glasses), intermittent exotropia or turning out of the eye, and stress. It is very rare for excessive blinking to be a sign of an undiagnosed neurologic disorder.
