Smallville Season 3 Episode 10
Attempting to stop a robbery, Clark is temporarily blinded when he shoots off a burst of heat vision that is accidentally reflected back into his eyes by a piece of kryptonite and soon realizes his body has developed super-hearing to compensate for his lack of sight. However, as it was in the beginning with his other gifts, Clark doesn’t quite have his new power under control.
