Anderson Cooper went temporarily blind after an assignment for 60 Minutes in Portugal last week.
Cooper revealed on his talk show "Anderson Live" yesterday afternoon that he lost sight for 36 hours after spending two hours out on the water.
"I wake up in the middle of the night and it feels like my eyes are on fire," said Cooper. "It turns out I have sunburned my eyeballs and I go blind."
Cooper instagrammed a photo of himself yesterday telling fans he was injured from sunlight reflected off the water.
Here's the video of Cooper explaining what happened:
