3. Eye allergies

If the patient's itchy eyes have obvious seasonality, especially itchy eyes occur every year in the spring when flowers bloom, but there are no obvious itchy eyes symptoms in other seasons. At the same time, if accompanied by symptoms such as itchy nose, clear nasal discharge, sneezing, etc., it is mostly itchy eyes caused by allergic conjunctivitis.

4. Eye pollution

Many women who love beauty often have symptoms of itchy eyes, which is mainly because the eyes are seriously polluted. Many female friends have the habit of wearing makeup. Drawing eyeliner and applying mascara may cause pollution to women's eyes and cause symptoms of itchy eyes. In addition, wearing contact lenses often causes itchy eyes.

5. Eye infection

If the patient's eyes are accidentally infected with Bacillus subtilis, it will cause the patient's eyes to itch unbearably, be afraid of light, shed tears in the wind, and when the eyelids are opened, the patient's eyes will have obvious congestion and swelling, affecting normal vision.

For example, dust, hair, drugs, bacteria, viruses, and irritating gases directly invade the surface of the eye and cause reactions.

7. Cold symptoms

When bacteria or viruses cause the blood vessels in the mucous membranes of the upper respiratory tract, such as the mouth and nasal cavity, to swell and become congested, the eyes will also have the same reaction, which makes the nerves on the surface of the eyeball sense abnormal stimulation, so there will also be an itchy feeling.
