I never got that about Cyclops. If his laser is red, and his glasses are red, wouldn’t that just let the light through? Wouldn’t he need green glasses?
Nah mate, the red lenses are reflecting red light, which is why they appear red. If they absorbed red light they would be absorbing incredible amounts of energy every second and heat up super fast. Because they reflect the energy the energy just goes back through the portals to the dimension that it came from. (Canonically.)
Editor: Why did you make his eyes red?
Artist: Coz of the lazers, duh
Editor: No, I mean why scientifically?!
Artist: (oh shit oh shit)
Editor: WE NEED TO GET OUR SHIT TOGETHER
Editor: CALL NASA, SPARE NO EXPENSE! (ten convoluted phone calls later)
Artist: ... and so the force beam reflects forcelessly off the glasses and back into its home dimension where his optic nerve lives....
see i've always had two pretty massive issues with this: 1) how tf does he see anything if he's got portals in his eyes, and 2) shouldn't there be a constant glow from behind his glasses whenever his eyes are open?
Obviously it's a cartoon and it doesn't matter, but once you try to explain things you kinda gotta come up with explanations for things like this..
Except, also canonically, his eyes project a beam of concussive, ruby-coloured force. If they're reflecting the blast, they should be experiencing a huge amount of force, and go flying off his face.
When he's in the field he has a helmet that has only one opening, and they call him cyclops. If the government ever comes looking for a one-eyed mutant called cyclops by his teammates, they'll never suspect the cool guy with red sunglasses covering his two eyes.
