Crazy eyes are an actual thing- in both Eastern and Western medicine:
en.wikipedia.org
"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.[4] 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."
""scleral show" or "scleral exposure," and may be caused by endocrine imbalance, physical trauma, aging, or cranofacial congenital anomalies.[8] It can also occur as a complication of plastic surgery to the eyelids (blepharoplasty).[9] For example, during removal of fat by laser surgery, too much laser energy ablating too much fat may result in scleral show."
