So we were all probably wondering why a certain character was missing a certain something from a certain light-detecting organ. Well here's our answer...
Nope. If you rewatch the scene, he was still wearing his hat while he was taking off the contact. Plus if you zoom in on the image, it's clearly circular like a contact and see-through.
I did rewatch it and made it giganticness to see what you were pointing out. I stand by the rebuttal that its the brim of his hat, which was blue... and hats curve ~ I'm not really doubting the contact idea because unlike in S1 where the Geass would just turn on, you tend to see his hand in front of his eye before it activates now. But that blue thing is his hat.

edit: though, at times it does look like he's poking at his eye but .. that blue thing is a haaaaaaat :D
