Coincidence....
I was just researching this at 3 am this morning... Rod photo receptor neurons are stimulated by white light while there are three cone photo receptor neurons. One each for long wave frequency (red), medium wave frequency (green), and short wave frequency(blue.)
My mind was comparing this to the frequencies of consciousness and the combinations creating a standing wave of white light, an intrinsic attribute of higher frequency consciousness and enlightenment.
Typical 3 am thoughts for me. I wake up downloading this info in my sleep.

I was fortunate to work at Texas Instruments during a battle between Epson LCD projector technology and the TI DLP chip technology, centering mostly on the education market.
The speed of the DLP chip was increased to over 110,000 “flips” per second, well beyond what the eye can perceive. Yet anecdotal evidence suggested that a very few people were bothered by the mirror flips (~digital light) verses LCD cubes (~analog light).
That the eye and brain can “see” something so far beyond what the “design” of the eye should allow is fascinating and still under study.
The second article discusses a woman who has a fourth cone (a tetrachromat) which enables even more color perception. I have seen that about 2% of women have some Tetrachromatic vision.
It seems that women in general, see about 8 times the shades of red that any man can. Why else 100’s of red nail polishes for ladies to choose from?
The eye and brain combo is one of the most fascinating areas of research to me.
LOL!!! Typical 3AM thoughts for me are definitely not appropriate to post here!
