Well, generally speaking, you should know that according to some doctors, grave eye disease is the most common form of hyperthyroidism. And in common, when it occurs, your eyes may look enlarged, because the upper lids are elevated. Of course, in some situation, one or both eyes can be bulge, and that can be very terrible. So you should pay more attention to it. In my opinion, it cannot disappear by itself, so you should try some ways to treat it. You can just have cool teabags to treat it. And then just have a good rest. Because it can be serious and dangerous, you may need to go and see the doctor. So that he can just give you some examination. Anyway, just be careful about it.
