Came across these articles talking about a LED Incapacitator flashlight that was being developed as a non-lethal weapon for law-enforcement and military. Interesting in that the symptoms they wanted this device to trigger sound almost exactly like what happens to me (and many of us on this forum) when we look at modern screens.
Not sure this is a "solution" to anything but might be interesting to learn more about what characteristics of light/pulses/etc. they had researched to cause the symptoms. Perhaps knowing that would allow for optimizing things in the opposite way for us not to have the symptoms.
From the articles: "TÂhe LED Incapacitator (LEDI) uses bright, short pulses of light to disorient the subject. Law enforcement officers have used strobe lights before. The LEDI is unique because it pulses in different colors (red, green and blue), spatial patterns, frequencies and intensities. The combined effect of the different colors and patterns temporarily blinds, disorients and nauseates the subject but doesn't cause any damage.
The brain has a limited rate or frequency by which it can receive and process visual information. If visual information arrives faster than the brain can process it, then the person becomes temporarily incapacitated. The frequency required to overwhelm the brain is about 7 to 15 hertz [source: Rubtsov].
Strobing disrupts the flow of the visual information in two ways. First, the brightness of the strobe's flash creates afterimages in the brain. If you look at a bright light -- please don't choose the sun -- and then close your eyes, you'll "see" an afterimage of the light. Second, the frequency of the flashing hovers near 15 hertz and impairs the brain's ability to process visual information, which produces disorientation and nausea. Once the LEDI is turned off, the nausea lingers for a few minutes as the brain recovers.
Law enforcement officials don't have to shine the strobe directly in the suspect's eyes. They just have to illuminate the target so that some of the flash points are near the suspect's eyes [source: Rubtsov]."
