Simple anwser: No, you can not change the colour of your eyes by just looking at your screen.
Longer anwser: Yes, it is possible to change the colour of your eyes. How? By altering the light is being broken. How do you do that? By altering the substance, angle etc. that your IRIS is at. The angle can be changed by altering the shape of your eyeballs/IRIS. This can be done by lasers(it has to happen very very precise). Or you could alter the substance because every substance has its own light fingerprint(Physics stuff, wont go into much detail).
Sorry if I am wrong in some ways, it's sunday and not a school day so the brain can be completely shut of
Oh yeah, to bring it simple: If the colour of your eyes can be altered by the colours you look at, then your eyes would be the same colour as the colour you stare the most at(which is not the case, I think)
Sorry puppy, looks like you're wrong. Turns out you can alter the chemical composition of your DNA just by subliminal messaging. Eye colour, hair colour, skin colour etc. Supposedly you can also think away those pesky cancer causing faulty genes too. So let's just do away with conventional medicine/physics/biology/laws of thermodynamics, and think happy thoughts instead....
Hmmmmm... Perhaps that over the course of multiple generations that the envirormental conditions have an influence on the DNA(This is done by natural selection). But those methods that are descibed in the article make no sense to me :/
To my knowledge, the only things that can change/alter DNA of a human are virusses and radiation. Viruses do this by injecting their own (m)-RNA into our cells to split into multiple infected cells. Radiation does this by pulling away elektrons from the atoms inside of the DNA's molecules.
But then again, those effects would only be noticable when the cells starts multiplying them(One cell is to small to notice with the human eye, except an egg).
Well... typical darker colours are dominant over lighter colours, dunno why but its the case most like of the time. Let's say that A=Brown eyes & a=Blue eyes and B=Brown Hair & b=Blond hair
Your fenotype is Blondhair & Dark eyes so that willl become Aa & bb or AA bb
this depends on your parents aswell, if you could tell me what hair & eye colour they have then I can make you a schedule wether your children have a change of getting blue eyes with blond hair or not
If you want blue eyes, there is always a thing called Colored lenses(Even tho they wont work that well on dark eyes, it's still worth a try if you want to)
