* Maybe I've just forgotten, but how did Lois and Clark decide to handle the fate of "Clark Kent" after Superman leaves Earth for New Krypton? I know they apparently didn't give it much thought, or at least QUALITY thought, given that their excuse for Clark missing Superman's farewell speech was that he was out seeing the reaction to the news...
* Clark did not become Superman until the near the end of the two-part pilot. Why, then, was he wearing glasses before that, when he was not trying to maintain a dual identity? The same question applies to the alternate universe Clark who was wearing glasses despite not being Superman until the end of that episode.
** He didn't become Superman, but was still going around saving people. The glasses help maintain his anonymity as no one would suspect the bespectacled, easy-going, nerdy farmboy as the same guy who stopped that speeding bus or rescued all those people from that wildfire.
** Also, John and Martha both wear glasses themselves. Clark's glasses lend more plausibility to the story that he is their biological son and possibly inherited their vision problems.
*** Well first and foremost, it's public knowledge that his parents adopted him. Also it's pretty obvious they couldn't be his parents give his obvious Asian features. Also as we saw in trip to the past, Martha and Jonathon didn't wear glasses originally. It's the result of old age. But I do agree that the glasses could still mask his identity out in public. It throws off the descriptions of him just a little. Can't tell eye color or some other features because the frames are obstructing them.
