The reasons for infant eye rubbing are as follows: 1. Conjunctivitis, frequent eye rubbing with bloodshot eyeballs, red corners and increased eye discharge is considered conjunctivitis and can be treated with tobramycin drops. 2. Ingrown eyelashes, some babies have more fat in the lower eyelid and the eyelashes cannot grow outward normally and curl inward, stimulating the eyeball and causing tearing and itching. 3. allergies, the baby eats or comes into contact with allergic substances that cause the child to be allergic, resulting in itchy eyes with eczema, parents should go to the hospital for allergen testing to avoid contact with allergens, and anti-allergy treatment can be given when the allergy is severe. 4. blocked tear ducts, the baby’s regular tears and yellow discharge from the corners of the eyes should be noted as a result of blocked tear ducts. Discomfort, generally after one year old can naturally heal. If the symptoms are not relieved after one year of age, you should immediately seek medical treatment.
