Exotropia is when one eye turns outward to the outside of your face. Its actually a form of strabismus or "cross eyes" Some people have esotropia where one eye turns inward toward the nose. There are also forms where the eye can turn up or down but all are forms of strabismus commonly known as cross eyes. When one eye turns rather than working with the other eye and focusing on whatever the person is looking at it causes distortion of vision and I have double vision but was told eventually the brain learns to "ignore" or turn off the extra image so I am not even aware of having double vision most of the time but I guess the eye doctor can tell.
