Dumb question, why is it the blogs have to have categories? And why is TV.com thinking there are words worthy of automatic censoring in my title? (I'm posting from MovieTome)
Anyway, about a year ago or so, I read about an idea that could explain why Clark could get away with using glasses as a diguise. Basically, his suit could be made out of special kryptonian material that would blur his identity to the average human.
This is great, but unfortunately, fridge logic sets in and you wonder why he wears the glasses to begin with if his costume is an effective enough disguise.
However, the concept had merit, and I refused to give up on it so easily.
I started thinking about this, and I came up the concept that his suit isn't powerful enough to conceal his identity completely, and someone like Batman would probably be able to recognize him. So he wears glasses as Clark for that extra line of defense.
Plausible, but just too convenient an explanation.
I kept working on it, and I decided that maybe the identity blur could be done by the shield so it wouldn't matter what other materials his suit was made of.
Yeah, that doesn't really help the issue, it just allows for more costume materials.
Anyway, after a while I just kind of gave up on the concept, but then I remembered an episode of Smallville where the ship that brought Clark to Earth turned out to be vulnerable to kryptonite as well...
The solution?
Clark's shield does indeed blur his identity to pretty much any human being, even Batman would be fooled. However, since his shield needs to be visible in order to work (i.e. can't put lead over it), it is vulnerable to kryptonite as well. The shield being affected by kryptonite would mean that its effects would be severely weakened, if not outright shut down. So Clark wears the glasses in hopes that anyone who sees his real face during kryptonite exposure won't make the connection.
Maybe I'm trying too hard to come up with a logical explantion for a comic book phenomenon, but at least I now know that it can make sense.
