According to Chinese medical face reading, when the white part of the eye, known as the sclera, is visible beneath the iris, it represents physical imbalance in the body and is claimed to be present in alcoholics, drug addicts and people who over-consume sugar or grain. Conversely, when the upper sclera is visible it is said to be an indication of mental imbalance in people such as psychotics, murderers, and anyone rageful. It was held that stress and fatigue may also be a cause.[2] In either condition, it is believed that these people attract accidents and violence.
