The reason for the frequent blinking is to consider whether it is because the work is more fatiguing in the near future, looking directly at the computer more, staying up late working, etc. In order to relieve the sore and uncomfortable feeling of the eyes and frequent blinking occurs. If it has nothing to do with the above factors, the first consideration should be related to the eye being stimulated by eyelashes, external stimulation or inflammatory stimulation, and the second consideration is that mental factors cause the eye muscles to move frequently.1. Eyelid impingement or eyelid entropion: common in children, impingement and lid entropion can stimulate the eye surface, thus causing the patient to blink frequently. If it is mild, you can observe it temporarily, but if it is more serious, you can consider surgical treatment; 2. Allergies: allergic conjunctivitis can cause patients to blink frequently. Allergic patients are exposed to external allergens, such as willow, pollen, dust, animal fur, etc. After the stimulation of these triggering factors, patients can experience eye itching, conjunctival congestion, conjunctival edema and other symptoms, and will blink frequently to relieve the discomfort. For treatment, patients are advised to get rid of the allergens, apply cold compresses to the eyes, and use anti-allergy eye drops or anti-inflammatory eye drops. It is important to note that if hormonal eye drops are used for treatment, this may lead to a series of complications such as elevated intraocular pressure; 3. Eye inflammation: Usually, a combination of eye inflammation may lead to discomfort and thus reflexive frequent blinking. Common diseases include: blepharitis, blepharitis, keratitis, conjunctivitis, etc. In addition to causing patients to blink frequently, they also cause symptoms such as congestion, redness, pain, itching, photophobia, increased secretions, and tearing of the eye. It is recommended that patients go to the hospital for symptomatic treatment, for example, blepharitis in the early stages of cold wet compresses of saline or boric acid solution, along with the auxiliary use of antibiotic eye drops and eye ointments, pay attention to removing triggers and avoiding irritating factors to relieve the blinking situation; 4, dry eye: such patients will have fewer tears, the eye has foreign body sensation, burning sensation and other uncomfortable symptoms, it will be relieved by frequent blinking; 5, mental factors: such as children ADHD can also have frequent blinking symptoms due to the patient’s abnormal brain activity, which causes the eye muscles to flutter and blink frequently, and the affected child often also has physical incoordination, irritability, inattention and other symptoms, and it is usually recommended to go to a pediatric or psychiatric psychiatry department for treatment.
