Is this true? Women see less colors than men, and they see washed out colors (and therefore "lighter"(?) image) due to their less developed iris.
The average human retina has five million cone receptors on it. Since the cones are responsible for colour vision, you might suppose that this equates to a five megapixel equivilant for the human eye.
But there are also a hundred million rods that detect monochrome contrast, which plays an important role in the sharpness of the image you see. And even this 105MP is an underestimate because the eye is not a still camera.
You have two eyes (no kidding!) and they continually flick around to cover a much larger area than your field of view and the composite image is assembled in the brain - not unlike stitching together a panoramic photo. In good light, you can distinguish two fine lines if they are seperate by at least 0.6 arc-minutes (0.01.Degrees).
This gives an equivilant pixel size of 0.3 arc-minutes. If you take a conservative 120 degrees as your horizontal field of view and 60 degrees in the vertical plane, this translates to ...
576 megapixels of available image data.
Curiously - as a counterpoint to this - most people cannot distinguish the difference in quality between a 300dpi and a 150dpi photo when printed at 6x4", when viewed at normal viewing distances.
So: although the human eye and brain when combined can resolve massive amounts of data, for imaging purposes, 150dpi output is more than enough to provide adequate data for us to accept the result as photographic quality.
But don't forget that women have more cones and men have more rods - I kid you not.Therefore the ladies see colours brighter than gents but can't see as well when it gets dark.

Women have better color perception. http://www.smithsonianmag.com/science-nature/where-men-see-white-women-see-ecru-22540446/
...and it is the retina, not the iris, that contains rods and cones.
[Edit] Having more rods doesn't allow men to see colors better in the dark. Rods aren't sensitive to color at all, only light and dark.Last edited by usually_quiet; 10th Jul 2014 at 11:05.

Many men (let's say, 75% of the straight ones) unfortunately see only two colors: pink and non-pink
