I have an irritating tiny brown spot on the white of my eye, above the iris... I can see it when I lift the lid. It just feels as though I had a piece of dirt or something stuck in it, I don't know where it came from. Will it heal itself? Or Should I see a professional? Is this a health hazard? I'm not having an vision issues accompanying it, I see fine.. it just feels like it would if I had a stye on the lid of my eye, but I know after seeing it, it's something much different. Please help!
