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.


  1. I LOVED that flowers link! I’ve never seen anything like that before.

    • Isn’t that amazing!

  2. 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.
