Do eyes change color?

Eyes do change color. Newborn babies have blue eyes, which in most cases will change to some other color, brown being the most prevalent color. And the eyes of extremely elderly people can also change back to blue. Aside from that, there are colored contact lenses which can artificially change eye color. I think what you are asking is that, a gorwns person eyecolor change color and possible, for what reason. One cause of a change in color is blood pressure. When someone is enraged or even happy, the blood pressure is known to rise or even drop. This flow of blood through the body can change to tone of one with light colored eyes. It would be harder to tell to a person with a darker pigment of eye. Light blue eyes can turn light green-bluish tone when that person is angry. Also the sun can make your eyes lighter.
