Wait, if Super Boy has X-ray vision, why doesn't he just look through Robin's mask/glasses?

i guess his is never bothered por robin never showing his eyes ;3

Perhaps Superboy doesn't care what Robin looks like maybe he respects his preverce and when you hear the word X-ray you think of your skelenon so maybe he if he had tried he might have seen Robins skelenon

Because batman expected everything and kryptonians can't see through lead so if Supey tries he'll only see the same domino mask.

He doesn't have xray vision it's inferred ( heat, like a thermal scope )

AHem. Infrared. Not X-Ray.
Yet
