Tripping too much in a short period of time gave my sclera (white part of eye) marks.

Is there anyway I can get rid of this? Visine doesn't do anything. My eyes also twitch and my vision isn't as sharp anymore. This I think will heal on its own though. Its these veins and grayish marks on the whites of my eyes that bother me. Is there anyway I can make them a pure white again?

I know these symptoms came only because of my abuse of these drugs. They are incredible tools, I was young, and just didn't use them properly.
