Sunglasses that could correct colour blindness

Camfer Wrote:Squirrel Monkeys, like all new world monkeys, are dichromats. So they took a dichromat and turned it into a trichromat.

that is interesting. thanks for the update! i will try to keep an eye on this research, this type of thing is very fascinating to me.


Camfer Wrote:Bees don't see red but do see UV. Many flowers have UV patterns that human eyes do not see. Do a search on UV pictures of flowers to see it. So in a sense, all humans are colorblind.

yup. compared to birds, for example, all humans are colorblind.

those UV pictures are amazing, by the way!

by the way, did you know that birds have a 4th cone cell type? or tetrachromacy, as it is. (and some insects and butterflies have been found to have 5 cones even). that makes 4 distinct primary colors for their vision. red, green, blue, plus the fourth. and everything is a combination of the simultaneous activation of these 4 cones. they can also see into the ultraviolet spectrum as a result.

I knew that about bees and birds detecting the near UV range and the 4 types of phororreceptors. Didn't know about the 5 types and butterfiles, though.

I haven't looked upon the kind of membrane proteins that respond to these specific wavelenghts, when I have a bit more time on my hands, I'd love to check those sequences.
