A case when the victim has seemingly lost all sight at a very sudden rate. The reason for the loss of sight is a mystery to the victim, yet for anyone else looking it is clear. This is caused by a whale appearing on the back of the victim and curling its tail so that the victim's eyes are gouged.
Person: Wow. This is a fight scene I wouldn't want to miss. (blacks out) Hey! what happened?
Doctor: I'm sorry to say this, but you've gone blind. WITH WHALES!
Person: OH MY GOD!!
