Nothing: Just like skin; parts of your white (sclera) may be a little brownish due to excessive melanosis or nevi. This is more common in dark skinned races. All of the white part may turn yellowish but never brown. Yellowish may be due to liver disease or hereditary anemias. See your family doctor.
