Well, I have to tell you that the black eyes can not occur without reasons. So you may get a black eye because of some potential factors. First, according to some researches, when blood and other fluids collect in the space around the eye, a black eye can occur. And when you are sleeping, it is easy to make your eyes collect blood and fluids around your eyes. In that way, when you get up, you will find the black eyes. You can try using ice to reduce the swelling caused by a black eye. Warm compress will also be effective for your black eyes, for they can make your blood flow smoothly. So you can just put a warm cloth on your eyes. Also, it is often caused by the injury to the face or the head. Then swelling and dark discoloration can appear.
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.:)
It is possible for you get the black eyes after you wake up in the morning. However, it is not normal. It means that there is something wrong with your body. The bruise part inner the body causes the black eyes. You should go to the hospital to have a check on the whole body.
Here's one response, sounds whacky to me!
you probably hit yourself while sleeping, when your asleep your brain releases a chemical into your blood to keep you from moving and acting out your dream but sometimes it releases it before you fall asleep or after you wake up sometimes not at all which causes sleep walking so you probably didn%u2019t get the chemical and hit yourself in the eye
