Anderson Cooper just went blind, but lived to tell about it.

The CNN news fixture went on assignment last week for 60 Minutes in Portugal, and relayed his (temporary) experience with blindness Tuesday on his daytime show.

"I am in this beautiful coastal area shooting this story for 60 Minutes involving the water ... I don't want to go into details [on] what the story was," Cooper said.

"But I am on the water for two hours shooting this story and it's an overcast day. I wake up in the middle of the night, and it feels like my eyes are on fire."
