The rocker baffled fans when he left the Bbc studios in London on Monday (12May14) as he covered up his left eye with the black pad.
Wilson has now revealed that he suffered a minor injury while filming a new promo for track Meanwhile Up in Heaven.
He says, "We were filming a video for our next single and I had a minor accident. I was on a bumper car because we were filming in a fairground and things got out of hand.
"You'll understand why when you see the end result. It wasn't even a stunt, it could have happened in the kitchen."
