This is called a "Sanpaku eyes"

sanpaku (三白) is a Japanese term meaning "three whites". It was introduced into English by George Ohsawa in the mid-1960s. It is generally referred to in English as "sanpaku eyes" and refers to eyes in which either the white space above or below the iris is revealed. The medical condition in which sclera can be seen below the iris is called "lower scleral show" or "inferior scleral show."

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. In either condition, it is believed that these people attract accidents and violence.
