Forum:What happened to Zoros eye? after the 2 year time skip.

He's blind in that eye now. We don't know what specifically happened to it.

It could be like the Gorgon sister Zoro and Sanji are each better at one type of haki and Zoro lost his eye training for Color of Observation haki. When the Kraken went to attack, Zoro was already countering even though he was limited in speed by the bubble.
