When Eye Blinking Is a Problem
Blinking is a reflex, which means your body does it automatically. You can also make yourself blink when you want to. Excessive blinking is when you blink more than you want to.
A number of things can cause excessive blinking. The most common cause in adults is a problem on the surface of your eye.
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. It also protects your eye by closing it to keep out dust, other irritants, very bright light, and foreign objects.
Babies and children only blink about two times per minute. By the time you reach adolescence, that increases to 14 to 17 times per minute. It stays at that number for the rest of your life.
You blink more when you’re talking, nervous, or in pain. You blink less while reading or when you sense possible danger.
There’s not an exact definition for excessive blinking. It’s usually considered excessive when it interferes with your life, vision, or activities.
