Does everything on the outside go all blurry/distorted? like, when you pull your fingertip in real close...y'know?

Try putting your finger tip on your nose and focusing on it...you go cross eyed and EVERYTHING goes blurry!! Perfectly normal! x

Focus on the background and the fingertip will go blurry
