The Baywatch star made the revelation in an interview with Britain's The Times newspaper, during which he said he is able to go unnoticed on the London Underground because he has to wear special spectacles due to an eye condition.

He said, "Today I took the Tube (London Underground)... And because I'm wearing glasses, because I'm having eye surgery (no one recognised me)."

Hasselhoff gave no further details about his condition or the surgery.
