Ok I know this is so random, I was watching New Adventures Of Lois And Clark the other day and I noticed Clark Kent move his glasses down so he could use his x-ray vision through a wall. Now my question is WHY?????? Why would he have to move his glasses when his vision can see through walls. It's crazy!!!!

Maybe because if he didn't, the lenses in his specs would refract the X-Rays and make them go out of focus?
He does the same thing when he fires laser beams from his eyes in the films as well.

Ah yes but if he didn't do that, he probably would melt his glasses
Posted by masseur
its not his cape and suit that gives him the ability to fly and yet he always changes into them to fly
I just think superman has to be superman, and not clark kent, when he is using his powers... simple as...?

He shouldn't do really since a laser is just a beam of light, the lens would focus it just like it does normal light.
Maybe the lasers are special cosmic rays or something

I am also WONDERIN' why to THESE IMMORTALS (specially those GUYS) . . . have to wear their TROUSERS - first before their BRIEFS/JOCKEYS
Really makes no sense 
Just try to imagine if they feel like PEEing prior to a fight

I think it is something to do with changing in a small darkened area... I have done it a couple of times in the early morning trying to sneak out before I have woken someone...

Come on... we have all done it... ;o)

I agree with cyco with the refraction issue, but I'm not really sure if lenses really affect x-rays the same way it affects light -- i believe it behaves more like a radio wave rather than a light wave.
I also don't think the laser passing through the glasses will make it melt. It will only refract the laser.
Superman has to wear the cape when he flies because it makes the flying scenes and effects easier to create and more realistic.
These are really serious issues we're dealing with here

I'm off to watch the Superman Ballet next weekend, our Maud and me will be sat behind a lead plate, there's no way I'm letting him perve at my missus!

It would be very funny if Superman got up in the morning after a late night and instead of putting on his Superman cloak under his usual suit, he wore them on the outside then went to work, with the glasses

@blackspot
You're absolutely right, a quick google tells me that "Lenses use refraction to focus light, but glass and other materials cannot refract X-rays."
Back to the drawing board...
Posted by rockygali
what i suggest is that...
Clark should wear frames... with no glasses... just to save time moving the glasses down and do whatever it is that he would like to do...
good thing tho, he doesnt shout up up and away no mo......
Posted by himlims_nl
maybe he should fly against walls if he didnt'

I think because its a convex lens that it spreads out his xray vision and Superman being the superhero he is, doesn't want to look through everything that might be in his path of vision, even Lois Lane. So without the glasses on he can control what he wants to look through....
Posted by Cycovision
Well, no because that's what refraction is
glass lenses don't spread x-rays out apparently.
Any more ideas?

You assuming that these 'x-rays' are coming from outside and entering his eyes through his glasses.
I thought he had X-Ray vision, whereby it was all in his eyes; light would enter his eyes in the normal fashion, then his x-ray vision would process it.
I don't think he actually sends out x-rays from his eyes, or does he
So, its my guess that the glasses he wears are part of his disguise as Clark Kent and to make it more realistic, he has chosen authentic specs, with lenses in them like the bottom of lemonade bottles, so he has to remove them to see properly.

Come on, real x-ray doesn't work like that, he uses some other means unknown to us. And i suppose a pair of glass lenses would not distort his vision in any way. So the reason he lowers his glasses may be to distinguish the two characters (Clark and Supes) apart, as Masseur has previously stated.
Posted by Cycovision
No, no, no you're missing the point!
We're not talking about dramatic effect and director's skills here. What's the science behind it in superman world?
I should imagine that he does emit something from his eyes which go through the things he wants to see behind at will, and reflect off the other things that he actually wants to see.
In which case, my original assumption may be correct, the glasses might interfere with his special rays.
Posted by gabbyevs
i wanna know where his clothes go to when he spins round to change
he always has endless supplies of suits!
Posted by procterdc
Yea you would have thought that Lois or Jimmy would have found clarks clothes and put 2 and 2 together... or even better the amount of time Lois spends with Superman AND Clark, she should have realised he is Superman hmm lets say maybe the 2nd time she saw him lol
On a different note, anyone seen Superman:Doomsday yet?

Well, there are two possibilities in my mind.
1. Superman has actual xray vision, meaning that he can emit xrays from his eyes at will and anything that reflects xrays back is visible, and anything that doesn't is invisible. (this is how an xray machine works). This is the most likely intent of the original author. Supporting evidence: in the 1950's you could often find x ray machines in chemists or shoe stores. They used the xray machines in shoe stores to see if the shoes fit properly and in chemists as a slot machine that people could put in a penny and slip there hand in and see their own bones. In those days xrays were not understood to be as dangerous as we now know. After a few years, people working in shoe stores and chemists with xray machines had high incidence of tumours form, so they eventually realised it was the xray machines and they stopped using them in this way. However this shows that at the time of superman being created, there was no inderstanding that superman's xray vision would actually be highly dangerous to the people who he spied on with his xray vision
2. Superman's "xray vision" is actually in the "far infrared" spectrum and not the xray spectrum. This would mean superman could see any object that emits even small amounts of heat, if it is behind a wall or object that emits less or no heat. This would be necessary to explain why superman isn't hit with a class action for compensation over causing tumours in hundreds of innocent bystanders. Also, I believe infrared is affected by glass (since you can take an infrared photo and the glass lense is able to focus the infrared rays)

One more issue with Superman . . . why is it that he just let his CHEST accept those bullets if he is fired upon by guns BUT when somebody throws a GUN at him he . . . docks
Posted by $herry
When superman was created, it was an ACTION COMIC...not a science journal...who the heck would pay attention to scientific explanations?
everyone doest work like marvel comics
So forget the science...its just about a superhero from a planet about which we know nothing with powers about which we know nothing and with a dressing code about which we know nothing and common sense about which we know nothing...
Posted by procterdc
I'd have said it was Superman who didn't know about the dress code, wearing his underpants on the outside lol
Posted by blackspot
my theory is that superman's so called "x-ray vision" is not really x-ray the way we know it (as max pointed out). I believe he has the ability to vary the frequency of the ray that his eyes emit (and receive) so that it penetrates different objects of varying characteristics.
it's like a combination and perhaps a very advanced variation of sonar and ordinary human vision. if he wants to see something his eyes emit a signal with a frequency (or other characteristic) that doesn't pass through the object he wants to see, instead it will be reflected back to him and the receivers / sensors in his eyes will receive the reflected signal and his brain will interpret it and he make him see the proper image. if he wants his vision to pass through something he must change the frequency or other characteristics of the beam his eyes will emit such that it passes through the blocking object but will reflect on the object he wants to see.
makes sens to me, don't you think?

Superman wears a bulletproof supersuit with supercape which as we all know are bulletproof, if a gun moving at high velocity hit him on the noggin, it would leave a nasty bump. What I want to know is, Why don't the baddies learn from their mistakes and shoot him between the eyes? Has superman a bulletproof eyebrow?

I don't think the suit protects him from bullets since, in the first Superman movie he caught a bullet in his hand when a mugger shoots Lois in an alley way
edit: oh yeah, and gets it in the eye too in Superman Returns
(thanks Dicky)

@ Dicky,
I said between the eye's! He's not got his glasses on, so the bullet proof contact lenses saved the day.
Posted by lastikcizme
Yeah, i got those same contacts too..! I bought them against shark attacks, though..

Look, one thing we all ought to be able to agree on, it's not Superman's suit that makes him strong or bullet proof. There are many examples where he has used his powers without his suit, including flying, bullet-proof, super strength etc.
His suit is also super strong, because it came from Krypton with baby superman. Martha sewed his baby rug into a superman outfit - which shows the baby rug was made from a woven fabric, since the sewing needle couldn't have penetrated the fabric otherwise.
So BOTH superman and his suit are bullet proof.
Posted by Twometre
The suit is definately not bullet proof bt he is bullet proof himself. It is activated when a need arise. His powers are controlled in his mind. Have you ever heard of the power of the human mind? Remember that he is super and semi human. His parents adopted him when he fell from nowhere. Shooting him between his eyes would not work because he is too fast and he catches the bullet as masseur said. However why is it that they put glasses in his family.

The suit is bullet proof because he has used it to protect Lois Lane and other people. But Superman is also bullet proof. He could let a bullet hit him between the eyes if he wanted to; it would just bounce off.
Superman is not human or even semi-human. He is Kryptonian, a race from the planet Krypton.
His powers don't come from his mind, they come from his physiology. Superman is from Krypton, a planet with a Red Giant sun. Any person who is born under a red sun, has superpowers when they come to Earth. That includes any Kryptonians who have come to earth, including Kara Zor-El (aka supergirl, superman's cousin) http://en.wikipedia.org/wiki/Supergirl
Also, Krypton had much heavier gravity than earth, which also accounts for Superman's much stronger musculature. When exposed to Kryptonite, superman loses his powers. Kryptonite is a meterite that has come from the Planet Krypton (which exploded just after baby superman was sent to earth).
