LOL, as usual, you will not get the black eyes when you wake up, but if you get it someday, just relax and do not feel surprised, because there are some reasons why you get the black eyes. For example, if you have the habit of night-walking, there will be more possibilities for you to get the black eyes. In other words, when you are sleeping, you cannot help going somewhere or do something. If you are not careful enough, you will make yourself hit somewhere then you will get black eyes the next morning. Of course, you will not remember what happened during your night-walking. Also, there is no other problem with you or your eyes. What you need to do is doing some ways to clear the black eyes, for example, you can use the ice cubes wrapped with clean towel putting them around your black eyes, and then the black eyes will go away within one week. Good luck.:)
