Revealing mistake: There are numerous times throughout the series where the supposed big city of Metropolis is actually just a back lot set and none of the buildings are more than a couple of storeys high. Quite often the green hills of Southern California can be seen beyond the set and between the buildings.

Perry: Real nice kid, millionaire by the time he was your age.
Jimmy: Yeah, well I had the mumps in sixth grade, kind of slowed me down.
Trivia: Had the show carried on for a fifth season, it would have been revealed that the baby that was given to Lois and Clark was actually Kryptonian royalty and was given to them to protect the baby from assassins.
Question: Whenever Clark uses his X-ray vision, why does he lower his glasses? Lowering them when he uses heat vision is understandable but there's no need to do it when Clark uses X-ray vision.

Answer: I don't recall if it was ever mentioned in an episode, but it's possible that the frames and/or lenses of his glasses are lined with lead, the one compound his X-ray vision can't penetrate. Speculative, of course, but it likely would have been done at a point in his youth when he wasn't in complete control of his powers.

I think the other answer has good speculation. I would add it could also just be an "acting gesture" that Dean Cain utilizes as part of his Superman character and not because there's any practical reason. That way, the audience immediately recognizes what he is doing.
