The problems in eyes should not be ignored. First, consult a doctor to make sure your eyes are healthy, because double vision can be caused by some eye diseases such as myopia, astigmatism, dry eyes, cataract and eye injury. Second, if you don't have any serious eye diseases symptoms, your double vision may be caused by over use of eyes. When you long time focus something, your eyes may get tired easily, thus you may get blur vision or double vision. So you should let your eyes have a rest to relax your eyes or do some eye exercises to accelerate blood circulations and strengthen eye muscles. As your double vision is temporary and not serious, it will recover by itself if relax your eyes.
Well, yes, in some cases, double vision can go away by itself. So you do not need to worry about them. Normally, when we look at an object, the muscles of the eyes co-ordinate with each other to focus on the same object. The brain on receiving information from the eyes processes it and come up with a 3 - dimensional image. But when you look at any object, you see its two images rather than one. We can say that as double vision. There are many reasons which can cause the double vision, such as alcohol, stress, and injury. And for some normal reasons, it will just go away by itself. But it is caused by some other reasons, such as injury, it need to have some medical cares.
As we all know that double vision, also called the diplopia, is a common problem we confronted in our daily life. Like me, I often get the double vision, for example, when I do not sleep well at night, the next day, the double vision will have a date with me. As usual, the double vision will go away after our take some actions. The easiest way you can make the double vision go away is doing some eye exercises. After take this ways, the double vision will go away in about one hour. If you really worried about your double vision, or you find it do not go away within long time, you had better go to hospital asking help from the doctor. Good luck.
Double vision is dangerous to survival, therefore, the brain naturally guards against its occurrence. In an attempt to avoid double vision, the brain can ignore one eye. Due to the brain's ability to suppress one eye, double vision can appear to go away without medical evaluation or treatment. The causes of the double vision however are very likely still present and loss of vision in one eye can occur due to lack of treatment. The loss of vision in one eye can be temporary or permanent depending on detection and treatment. It is in this way, that diplopia contributes to loss of depth perception and binocular vision, amblyopia (lazy eye), and/or strabismus (deviating eye).
