The white eyeball is actually the sclera, and the yellowing of the white eyeball is the yellowing of the sclera for the following reasons: 1. Some drugs can cause the yellowing of the white eyeball, for example, the drug Adipine for malaria can cause yellowing of the sclera; 2. Some people especially like to eat pumpkin, carrots, oranges, mangoes, tomatoes, and eating too much will also find yellowing of the eyes, which is due to the pigmentation caused by excessive carotene that cannot be metabolized quickly in the liver. It is not a pathological condition. If the palms of the hands are also yellow at this time, most of them are caused by food; 3. Pathological jaundice, mainly seen in patients with liver disease, bile duct disease and hemolysis, need to go to the hospital for examination.
