What can i use to make the sclera of my eye white again?

See DR immediately: Yellow eyes are not normal, and nothing you can do topically will help change the color back to white without seeing your eye doctor immediately. S/he can evaluate it, and discuss further medical workup to check for jaundice, or bilirubin build up that causes the yellowness, and identify the source first. That's the fastest way of getting the yellow out of your eyes.
