“The eyes are the openings to the liver. People who suffer from eye problems usually suffer from liver disorders and vice-versa. As anger is a symptom of liver dysfunction in Taoist theory, people who use their eyes too much may become angry… The eyes, specifically their movements, are indicative of an individual’s intelligence. People who are clever have large eye movements and are always exploring their environment. Slow eye movement, or a lack of eye movement, indicates a repressed level of intelligence, which may also be helped through stimulation of the eyes.” source
