I've had a "freckle" in the vision of my one eye for as long as I can remember. It's always in my peripheral of my right eye and it has never gotten bigger or smaller or darker. It only moves when I move my eye to look at something.

I've had glasses for years and dozens of different people looking at my eyes, but they have never said anything about it or noticed anything different.

Any suggestions as to what this might be? It's a small dark circle that is easily ignored and barely noticeable in my vision, but I am a bit concerned because I'm getting LASIK soon.

 

So, overall: A brown colored speck in my vision moves with my eyesight and it has been there for over 20 years. What could it be?
