Iris Infiltration

Eye color is fascinating to me. Why are different eyes different colors? I don't mean how genetics change the pigments that change the color of the iris I am talking about the fact that there is even a variation.
 Does that variation affect the way we see? 

If someone has blue eyes is their vision tuned slightly differently than someone with green or brown eyes? 

After thinking about it a lot and some research I'm going to go with, yes

The Iris is a muscle that is colored and opens and closes to allow more or less light in through the pupil (hole.) The light then goes through the lens and is focused on the back of the eye. The light that goes through the Iris would be slightly tinted by it's color like stained glass windows.

 Even if the Iris was completely opaque  and no light could go through it's fibers the light would still be tinted by it's color since it is bouncing around and off of the iris (on both sides) and within the eye itself.  

It would be like if you had a glass full of a colored liquid and shown light through it - the reflection on the other side would be tinted that color. If the glass was full of clear liquid but the glass itself was tinted the light going through would also be tinted that color. If both the liquid and the glass were clear and you placed an object in the glass that was a certain color - the light going through would still be tinted by that color. So it seem like regardless of how much or if any light going through the iris - the light going through the eye would be affected by the color of the iris. 

This would mean that two people with two different colored eyes would see the same thing slightly differently from each other. Similar to how things look different through different tinted glasses. 

This is how we are able to perceive 3d with anaglyph glasses. One lens is tinted red and the other blue. Then a picture is taken through a red lens from the perspective of one eye and another is taken from the other eye though a blue lens. When these two images are combined you see a picture with both blue and red. When you put on red and blue tinted glasses it reconstitutes the image into 3d because it makes each eye see the same object from two different perspectives at the same time. 

This is a picture of the same thing taken from each eye. If you combine them together by crossing your eyes it will turn 3d and appear to pop out of the screen. This is how you would see things if you cross your eyes. (try it) 

This is both pictures combined into one. This is how you would see things if your mind did not automatically combine the image from each eye into one. 

This is what it would look like if you took a picture from each eye through red and blue tinted lenses. If you look at this through red and blue 3d glasses it will turn 3d. 

This is what each eye sees through the red lens and then through the blue lens. Notice how different they are. If you were to put on red and blue 3d glasses and close one eye you would only see the red version. If you close the other you would only see the blue version. When you look through both at the same time you see both that the same time and they combine. 

This older blog post demonstrates this more clearly:

This room was illustrated with different colored images. If you see it with red light you would see the red images and if you see it with blue light you would see the blue images. 

Sooo what i'm thinking is that while not as extreme our eye color would affect what we see in a similar way. Someone with blue eyes would have their vision slightly tinted blue. This wouldn't make it so they couldn't see other colors but that certain complimentary colors would stand out more than others (especially conflicting colors.) 

This is similar to why people say that they eye color seems to change with the color clothes they are wearing. "That really brings out the color of your eyes." 

"1. If your eyes follow the movement of the rotating pink dot, you will only see one color, pink.
2. Green Catastrophe: If you stare at the black + in the center, the moving dot turns to green.
3. Reality Shatter: Now, concentrate on the black + in the center of the picture. After a short period of time, many if not all of the pink dots will slowly disappear, and you may only see a green dot rotating.

What does this tell us about the nature of reality? There really is no green dot, and the pink ones really don’t disappear. If our brains are so easily fooled, what aspects of reality are we missing?" -

What Leonardo had to say about Color:

"The appearance of a color can to a certain extent be modified without directly acting on it with any actual material mixture. One need only put it next to another color which, depending on whether it is similar or opposite, will attenuate or enhance its intensity. Thus, if one paints a small square of paper in a rather dull red and then puts it on the pure red disc, the tint of the former will seem much more lusterless than if it were seen separately. But if one places this same shade on a sheet of paper colored with its complementary in blue-green, it will be exalted to the point of seeming as bright as the pure tone of the disc. These are effects of contrasts.

When two surfaces of different color are juxtaposed their adjacent edges are mutually tinged with the complementary of each color. And this occurs by virtue of what we have just ascertained in the previous experiment, namely: that the edges of yellow turned blue-violet. At times, when the colors are still wet, not only the edges, but even the entire surface of each color may be altered. On account of their vividness, our eyes cannot stand their tiring effect for long, though long enough for them to be able to see the secondary color. The eye goes from one to the other, thus carrying with it the complementary element of the neighboring color. In addition to a simultaneous contrast, there is here a subsequent contrast.

On making the colors in your paintings vivid and beautiful Again with reference to those colors which you want to be beautiful you must first prepare the perfectly white ground; and this I say of those colors which are transparent, because those that are not transparent do not benefit by a light ground; and the example of this is taught by the colors of glasses, which, when interposed between the eye and the luminous air, show themselves to be of excellent beauty, which they cannot do when they have shady air or other darkness behind them.
Which part of the color must reasonably be more beautiful If a is the light, b will be lit in line by this light; c, which cannot see this light, sees on y the illuminated part, which we shall say is red; being thus, the light which is generated on the part will resemble its cause, and will tinge the face c in red; and if c is likewise red, you will see that it is much more beautiful than b; and if c were yellow, you would see created an iridescent color between yellow and red.

Upon how reflected color is simple but is mixed with the species of other colors No color which reflects in the surface of another body tinges that surface with its own color, but will be mixed with the intersections of the other reflected colors standing out in the same place: as the yellow color a which reflects in the part of the sphere c or e, and in the same place reflects the pale blue color b. I say that because of this mixed reflection of yellow and blue the percussion of it concourse will tinge the sphere: if it was in itself white, it will turn green, because it is proven that yellow and blue mixed together make a very beautiful green."
