What is the reason for itchy eyes?

In our daily life, when our eyes are particularly itchy, most people think they have trachoma. Trachoma is an infectious disease. Due to the improvement of sanitary conditions, it is rare around us at present. There are three common reasons for itchy eyes: first, there is inflammatory stimulation of conjunctiva; The second is eye fatigue caused by excessive use of eyes; The third is allergic conjunctivitis.

Allergic conjunctivitis is an inflammatory reaction caused by conjunctiva allergy to some external substances. Conjunctiva is commonly known as "white eyes". Often exposed to the outside, it is easy to contact with some allergic substances in the air and cause allergic reactions, which eventually leads to inflammation. Common allergens in the air are pollen, dust and animal feathers. Spring is the day of bloom, and there are often pollen flying and catkins flying in the sky. In spring, warm winds blow gently, and at the same time, allergens in the air are brought to our eyes. If you want to go out at this time, you must pay attention to protecting your eyes to prevent and reduce allergic substances from entering your eyes. The specific method can be: 1. Don't go out in windy weather; 4. When something like catkins is flying in the air, don't look up, try to lower your head and squint your eyes to prevent such things from falling into your eyes; 3. You can wear light sunglasses if you can. This not only harmonizes beauty with the breath of spring, but also prevents pollen, dust and other substances from blowing directly into the eyes.

The most common symptom of allergic conjunctivitis is itching, even a strange itching; Followed by jealousy, tears and foreign body sensation. If you have these symptoms, don't rub your eyes more or wash your eyes with salt. You should take some anti-allergic drugs locally. Of course, it is best to go to the hospital and be treated under the guidance of a doctor.
