Why is the Universe Comprehensible?

93. The device only exists *NOW* if people are willing to trade color blindness for legal blindness.

The ability to perceive color is NOT DEPENDENT UPON PRECISE SPATIAL CONTROL of the signal/data interpretation. If you look very carefully at my posts, you'll find I made no claims regarding that at all, and your point is meaningless, because since I made no such claim beyond PERCEPTION OF COLOR, it doesn't falsify anything I said at all. Bravo.

OK. If you want to pick nits, here is your original claim:

Colorblind people are capable of discovering light frequencies.

The device you're citing is for blind people, people who remain legally blind after the device is implanted.

From wikipedia:

In North America and most of Europe, legal blindness is defined as visual acuity (vision) of 20/200 (6/60) or less in the better eye with best correction possible.

And, from the cited article:

"While high-fidelity color vision is a long way off, some patients with retinal prostheses have so far been able to read large fonts (with visual acuities on the order of 20/1000) and complete daily tasks in ways that they could not before treatment,” postdoctoral scholar Dr. James Loudin told Photonics Spectra. The research team hopes to achieve visual acuity better than 20/200 and is focusing its efforts on assessing the visual acuity and contrast sensitivity in vivo, said Dr. Daniel Palanker, an associate professor of ophthalmology at Stanford.

Seidensticker's examples remain untouched.

This is becoming tedious. If you can raise an actual issue in the future, I'll respond. Going round and round in circles arguing that a device that would legally blind a currently legally sighted color blind person is some resolution to color blindness is ridiculous.
