Well, we can say that double vision can be caused by dry eyes. Generally speaking, after the hard work, your eyes feel tired and strain, even have the double vision. When people work hard for a long time, it is easy to have eye strain because they have to focus their eyes on one thing for a long time. Then, the eye strain will just decrease the blood flow and in this way, your eye will become blurry, and also become dry eyes. In this situation, the double vision can happen. So in my opinion, if you have dry eyes, you should pay more attention to it. In some cases, you also should go and have an eye exam. So that you can find a good way to treat them.
