Blinking more frequently can be annoying, but it's rarely a sign of a serious issue. Some possible causes of more frequent blinking include: eye irritation, due to irritants in the air, dry eyes, a scratch on your cornea, inflammation of your eyelid or iris, having something in your eye, or other reasons.

Why do I keep winking randomly?

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.

Why do I wink a lot?

You naturally blink more when you're in pain. Bright light and changes in temperature also cause it. You blink more when you're talking or nervous, too. But if it happens a lot, you should see an eye doctor, also called an ophthalmologist.
