Frequent blinking mainly results from entropion and trichiasis, tic disorder, eye inflammation, eye fatigue, and habitual blinking.
If there is a phenomenon of entropion and trichiasis, the eyelashes often touch the eyeball, causing discomfort and leading to frequent blinking. If there is an uncontrollable contraction of another part of the body in addition to frequent blinking, it is likely to be a tic disorder.
1. Entropion and Trichiasis: If there is entropion and trichiasis, the eyelashes may touch the eyeball occasionally, causing a foreign body sensation in the eye. This will lead to frequent blinking to alleviate the sensation. Frequent blinking caused by entropion and trichiasis usually improves gradually with age, but if the entropion is severe, surgical correction is often considered.
2. Tic Disorder: If frequent blinking is accompanied by uncontrollable contraction of a certain part of the body, it may be caused by a tic disorder. It is necessary to pay attention to this situation in daily life, and timely treatment is required if frequent blinking is caused by a tic disorder.
3. Eye Inflammation: When the eyes are infected by bacteria or viruses, conjunctivitis, allergies, and other inflammatory conditions may occur. Frequent blinking may occur due to continuous irritation by the inflammation, which may also be accompanied by conjunctival hyperemia and eye secretions.
4. Eye Fatigue: Overuse of electronic products can easily lead to eye fatigue. When the eyes are in a fatigued state, they will involuntarily blink to relieve the fatigue.
5. Habitual Frequent Blinking: Habitual frequent blinking is common in children and is generally not caused by disease. It is just a simple habitual blinking and has little impact on the body. If a child has habitual frequent blinking, parents can help them overcome this bad habit.
