Replying to So i have a scar on my eye.....

i dont know if it is actually a scar, but it is like i clear tube that i am looking through.. it doesnt impair my vision at all and id say 75 percent of the time i dont see it.. if i am looking at white it will appear, and it has been there for at least a good 10 years... any thoughts on what it may be.. ill try and do a photoshop of what it looks like when i see it. and you cant see it looking at me, no eye doctors have said anyhting but ive never mentioned anything
