Well, generally speaking, bulging eyes are named as Proptosis, or exophthalmos, and it is the bulging out of one or both bilateral of the eyes. In common, you should know that there should be no visible white between the top of the iris, which is the colored part of the eye, and the upper eyelid. And when you can see white in this area, it is usually a sign that there is abnormal eye bulging occurring. So you can just check this with your own situation. By the way, you should know that if a person suddenly develops proptosis, especially in just one eye, it is considered a very serious problem. At that moment, you should go and see the doctor as soon as possible.
