Is the symptom of dry eye in Gansu just dry eye?

I believe that most people often feel dry eyes in their daily work and life, but this is not necessarily dry eyes. The healthy tears of normal people have not only water layer, but also lipid layer and mucin layer. The abnormality of these ingredients, or the disorder of more factors, may cause dry eye. Don't confuse "dry eye" with ordinary "dry eye"! Dr. Aier of Gansu said that dry eye is not only manifested as dry eyes, but also symptoms such as burning eyes, foreign body sensation, visual fatigue, jealousy, tingling and increased secretion.
