^ From what was said in the interview he only got this power because of the episode from season three (Whisper) where he had to wear glasses. They had negative feedback from women with that choice to put him in the glasses and Welling was able to negotiate into his contract an override of clothing options for his character. That's also why Clark got away from plaid.
Negative feedback has an effect on Smallville ? Or is it just negative feedback from women ?
Most of the Smallville viewers I've ever encountered have wanted Lana gone, we've only just gotten rid of her and then they bring her back!
There are a million things wrong with Smallville to fix before you get to Clark wearing glasses in one episode
