Children's eyes are itchy. What eyedrops should they use. Children with itchy eyes need to find out the cause before they know how to treat it. There are several common reasons for children's itchy eyes: first, the allergic reaction of the eyelid or conjunctiva to some external allergens. Common allergens include dust mites in the air, animal feathers, pollen, some chemicals, cosmetics, drugs, etc. In particular, allergic conjunctivitis can cause obvious itching, sometimes even extremely itchy, and you must rub with your hands. If this happens, try to get away from the allergen and use some antiallergic drugs for treatment. If the itching is serious, you can also use some eye drops containing hormones appropriately. Second, some children have itchy eyes, or some problems such as chronic conjunctivitis, trachoma, conjunctival calculus, etc. Generally, some antibiotic eye drops or anti-inflammatory eye drops can be properly used to dot the eyes.
