Why do your eyes pop out?

Answer 1

If you mean that the eyes look protuberant or "bugged" out, some people have that as a normal feature of their facial bone structure. In other cases, it can be a sign of a disorder called Grave's Disease, an autoimmune disease that affects the thyroid gland. This common sign of exophthalmos (sometimes called proptosis), or protuberance of the eyes, often is the first indication of Grave's Disease. There are too many other possibilities to list all conditions that can involve this sign.

If only one eye is bulging, it can also be a sign of a tumor behind the eye.

An eye examination by an Ophthalmologist is recommended when this condition either of one eye or both is first noted.
