Abstract: A system for generating light with reduced physioneural compression. The system includes a first light source operable to emit light within a first wavelength range corresponding to a first photoreceptor and a second light source operable to emit light within a second wavelength range corresponding to a second photoreceptor. The system includes a controller functionally coupled to each of the first light source and the second light source. The controller is configured to alternately operate one of the first light source and the second light source with a duty cycle that is less than a response time of the visual cortex, but greater than a response time of physioneural cells, optionally including a latency between operation of light sources. The system may further include a third light source corresponding to a third photoreceptor.
