Slight yellowing of the whites of the eyes may occur in individuals who have not been exposed to external environmental factors for a long time, such as prolonged wind, sun exposure, or ultraviolet radiation, which can affect the normal color of the sclera. People with poor lymphatic metabolism and circulation are also prone to yellowing of the eye whites. Additionally, slight yellowing of the sclera can be caused by biliary tract diseases or liver disorders.
