If you are unwell because of crying, please stop crying and let smile on your face. To determine the causes of your itchy eyes during crying, the steps as follows may work: firstly, think over whether you have any basic eye problems or get eye disorder recently or not, and then ask your family if there any inherited eye disease your whole family owns. Well, if these possibles all not exist, I think you have nothing wrong with your eyes. You feel itchy when crying just because the nerves about your eyes are so tired and the films are blockage. At that moment, the only thing can you do is stop crying and take a good rest in order to relax your nerves and smooth films. Personally, crying a while every two weeks is really good to reduce bad mood and relax. However, constantly crying is harmful to your health and your mood and your spirit.
