What causes eye blinking symptoms?
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. Increased blinking, especially in children, may be a type of facial tic. Congenital glaucoma is a rare cause of increased blinking.
Eye blinking symptoms may also be caused by conditions occurring in the nervous system.
A severe decrease in blinking is seen chiefly in Parkinson’s disease, a brain disorder that impairs movement and coordination.
