Itchy eyes and dry eye’s are often two conditions, but the two conditions affect and aggravate each other. Usually, itchy eyes may be caused by dry eyes, but most of them are due to allergic conjunctivitis caused by allergies, which leads to itchy eyes. Anti-allergic treatment with Olopatadine drops, usually used 2-3 times a day, can improve the symptoms. If the eyes are dry and have dry eyes, artificial tears are usually used for alternative treatment. You can choose sodium glassate or lipoprotein-based artificial tear drops, such as Hailu or polyethylene glycol. If used for a long time, you can choose the preservative-free type, which will have relatively fewer side effects. In case of dry eye with combined allergy, you can combine two drugs, that is, Olopatadine and sodium glassate drops, which will have better effect.
