Why do i have a red circle around my avatar head?

[goemo]

Its kinda like being inside an eyeball.. How do i turn it off?

[DISLEX]

I have the same problem now! No one else can see it. It's driving me nuts.

[MisterJerome]

could you give more information? "red circle" is kind of vague. Do you perhaps have a screenshot?

[SugaryMess]

Ah, I remember this. It's when you leave one of those shooting range worlds where if you take damage, you get this red blurr on your screen. If you leave the world, the red circle follows sometimes. It's happened to me multiple times. I just close the game, then reopen, and poof. All gone.
