How am I seeing?
August 19, 2013
I saw this story from the New York Times on glasses that can correct some kinds of color blindness and I thought that was interesting.
It made me think about how different perceptions can be for different people. I used to drive myself crazy when I was a kid wondering about that. Were there some people for whom chocolate tasted terrible and liver tasted good, and what do dogs actually see, what about bees that can see ultraviolet?
I would have like to be able to see beyond the visual spectrum and wondered what it would look like if there were more colors. I was sure that there were, if only I could see them.
Here are some ultraviolet flowers.
And you can test yourself here with the farnsworth-munsell color vision test.
The image above is from the Ishihara color vision test. You can take that online, too.
If you were color blind would you buy the glasses? I would think seriously about it.

I LOVED that flowers link! I’ve never seen anything like that before.
Isn’t that amazing!
You’re inspiring me to reread David Lee’s _Nature’s Palette: the Science of Plant Color_.
Interesting – I’ll have to look that one up. Thanks.
