if, big if, you could swap over your eyes, left to right, what would the world look like?

From what i think i understand about the way the eye works, we have cells which can identify either red, blue or green light, which i guess corresponds to a certain wavelength (475nm, 510nm, 650nm), yet yellow light, for example, has a wavelength of 570nm. Is this picked up only partially by red and green receptors? If this is the case, technology using 3 colours of pixels in screens must be perfectly adapted to human eyes, yet a new type of television has been released with a yellow pixel as well. Would that offer any advantage to colour perception, or is it just smoke and mirrors?

When I wake up, the white of my left eye is always slightly pink. This isn't the result of blood pooling on the left side of my body as I invariably sleep on my right side. After 10 minutes my left eye is back to the same white as my right eye. My left eye can start out even pinker if I have drunk too much alcohol the night before, but it still reverts to white after 10 minutes. I'm not concerned - it has been like this for years - but what is the cause?

I read about the possibility of people having tetrachromacy and would like to know if a test similar to a Ishihara is possible on a standard RGB display.

My boyfriend, a blue eyed Swede, told me that if we were to have children, he or she would be more likely to get my brown eyes rather than his blue eyes, because the brown eye gene is stronger.  Is this true? And if so, does that mean that one day there will be no more blue eyes in this world?

Are my eyes really changing colour? And why is this? They were blue as a child but changed to green in my early teens. Now it seems that they are changing colour again if i look closely at my inner iris.

Since we have such different faces and body structures compared to dogs, how can they instinctively tell that the two spots on the upper portion of our faces are in fact our eyes, and not, for example, our nostrils?

Once when I put some classical red-green 3d pictures on our site I looked up on the Internet if they work for colorblind people. They do, as I expected. But there is more to that. It wasn't this link http://blog.modernmechanix.com/2007/07/20/glasses-let-color-blind-see-red-light/ but a similar one. Not red-green but red-grey or orange-grey glasses help to distinguish red because it looks bright to one eye and dakr to the other, so it gives a flickering effect.

So my question, couldn't people with normal eyesight also build glasses that help us to distinguish shades that look the same to us now? Like short-wavelength violet that is close to ultraviolet and a violet made op of blue and red? Or clean one-wavelength green and a green made of blue and yellow?

He is not colour blind and can see red laser point without a problem.
