All right, I think you must have been using your eyes in a wrong way. Because itchy eyes could be seen as a health risk sign, whch is resulted from bad use of eyes or some bad habbits. Anyway, twitching eyes are primarily derived from a lack of sleep, eye strain, fatigue, or some eye diseases, and that is complicated unless you try to get some medical checkup. And you must not rub your eyes, since that leads to infections.
When you rub the eyes, your eyes will feel itchy. Your eye twitches will make your eyes feel not comfortable. If you continue to rub them, you will find that your eyes nerves will be intense and your eyes twitches will become more serious. You should let the eyes have the good rest. In addition, you could use the eye drops to moisture the eyes and make the eyes feel bright and comfortable.
