Color vision is for seeing ... people!
What is color vision for? Why do we have it?
These are deep evolutionary biology questions, but answering them was key to our patented VINO technology.
In 2006 one of our co-founders -- back when he was at Caltech -- discovered that our (and many other primates') color vision is peculiarly optimized for seeing oxygenation modulations in the blood under the skin. Not to see blood per se, but so as to detect emotions and health states.
With our kind of color vision we could "read" our fellow humans better, by seeing into their underlying physiological state.
That's how we at VINO (formerly O2Amp) came to know what color vision is for.
And with that in hand, we were in the unique position to develop and patent technology that further enhances that signal, thereby aiding paramedics and other clinicians, and helping color deficients.
