Children who keep rubbing their eyes may have allergic or infectious conjunctival inflammation, inverted eyelashes or refractive errors. 1. After contact with allergens such as pollen, mites, etc. or infection of the conjunctiva by microorganisms such as bacteria, there will be obvious conjunctival congestion and itching, which will be manifested as children rubbing their eyes all the time, and it is necessary to give corresponding anti-allergy treatment with Olopatadine Hydrochloride, or anti-infection treatment with Tobramycin. 2. When children suffer from impingement, the direction of the eyelashes is abnormal, which can irritate the eye surface, resulting in foreign body sensation, itching, etc., and the impingement needs to be removed and treated. 3. Children with refractive errors such as astigmatism and myopia, which affect normal vision, may also have the abnormal behavior of rubbing their eyes all the time. It is recommended that frequent eye rubbing in children should be taken seriously if it does not relieve for a long period of time, and should be treated with targeted treatments after improving the slit lamp microscopy and other auxiliary examinations.
