How to get rid of brown spots on the white part of the eye/Sclera after vomiting? (Photo)

Over a year and a half ago I got very sick with the stomach flu which made me throw up a lot. I got a whole bunch of red dots in & around my eyes. They ones outside/around my eyes went away within a few days. The ones on the sclera turned brownish, and they have not even faded a little. What can I do or use to get rid of it? It's been over a year an a half! The sclera used to be white now I look horrible because of the brownish spots/stains. Please help! thank you!
