How much blinking is normal?
On average, most people blink 15 to 20 times per minute. This helps your eyes stay healthy by keeping them oxygenated and moist, and clearing out debris.

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.
Do we close our eyes when we blink?
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.
Is blinking too much bad for you?
Excessive blinking might be irritating, but it’s rarely caused by a serious problem. When it is, it’s part of a neurologic syndrome, and there are usually other neurologic symptoms. Blinking lubricates and cleans your eyes by spreading your tears over its outer surface.

Excessive blinking can be caused by the problems with the eyelids or front surface of the eye, habit, need for glasses, eye misalignments, or stress. It is very rare for it to be caused by an underlying neurological disorder.
Why do babies blink?
Blinking serves primarily to coat the eyes with tears and remove any dirt or debris from the surface of the cornea. So another theory is that infants, perhaps because their eyes are better protected by smaller openings or because they sleep so much, may require less eye lubrication.
What causes excessive blinking of eyes?
Most commonly, increased eye blinking results from eye irritation caused by bright light, dust, smoke, or a foreign body in the eye. Allergies, infections, and dry eye may also increase the rate of blinking. Conditions of stress, anxiety or fatigue may lead to increased blinking.

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.
