I would like very much to understand why all squirrel males are color blind or in other words why they don’t seem to inherit the 3 opsin genes from their mother

Ringo, how could you have UV vision?
Have you heard of anyone else who can?

Harlan,
Cool article! I’ve always wondered, as sometime’s colors are different shades than someone else is telling they are, if we all saw color differently. For instance, that I would see a particular yellow more sun like and you would see it as mustard color… I am near sighted and also notice a particular clarity when I do not use my contacts and read or look at things close (where it’s not blurry for me) I can see far more detail, like for eyebrow plucking But, anyways. Great thought provoking post and thank you Harlan for the link!
Robert,
As a pretty blind far sighted person (-5.5 in both eyes; contacts ~ I walk into things) I can say that I would much rather see blurry color’s than clear black and white. These studies are wonderful for the blind… Blindness is my second worse affliction fear (first is Alzheimer’s)
Another great post Ed ~ Thanks!

I wonder if its more important to see clearly or to see colors, or phrased differently, what’s worse: to be near sighted or to be color blind. I’ve also heard that there is a certain advantage to not seeing clearly, … near sighted people tend to see the world differently that our sharped eyed breathren, much like lefties and righties often have different brain hardware.

*I* have UV vision.
It’s not an advantage. For all intents and purposes, I’m blue/green colorblind. (Why? Because I can distinguish between shades that the rest of the world think are identical. How can I tell which color is different when they all are?).
Roses are striped. Tide soap is bright purple, and so are clothes washed in it. Moonlight is almost as bright as sunlight. Sunlight is excruciating.
I can also see the flicker in fluorescent light. Not sure if that is related, but the switchover from incandescents is already causing me problems.

Interestingly, there's some evidence that some women have *four* color cones, which gives them even better ability to distinguish colors. http://www.post-gazette.com/pg/06256/721190-114.stm

So, my kids can have UV vision (from birds), but I can’t, right?
Man, I want infrared and ultra violet vison so bad, so very very bad.
There’s eye transplants, no?
That said I’ll wait until the the technique is well established before I go under the knife/virus.
