Why is this Photoshopped picture of Paul Ryan's face so hard to look at?

Your brain expects a normal face with one set of eyes, one mouth, etc. The brain 'thinks' that its seeing double because of a focus issue, not because the picture is actually doubled up. Therefore, it tries to continually adjust focus to get you back to single-vision. Of course this doesn't work, because there is no focus issue to begin with, and all you get is an uncomfortable feeling.
