ShivaWind I assume it's some super strong stroby blue LED.

I can make one myself with an Arduino. Don't need their overpriced garbage.

    I would be more interested in seeing one created from a cell phone. You could put the app on google play and let teenagers dare each other to stare at the screen. It could be like the next pokemon go! all we need is a catchy name. puke-eh-man go! then again, does the world need weaponized smart phones?

      JTL he deserved it (and more). I was there when it happened and it still cracks me up

          degen He's strange man, that's for sure.

            AgentX20 Is there any way of confirming which phones have this and which don't? For example Galaxy S5 does not bother me while Galaxy S7 and S8 do.

                ryans I'm not aware of any foolproof way to detect which devices will be troublesome. This is due to different people being sensitive to different aspects of the displays coupled with vendors using different supplies on the same device, and with there not being any real clarity on what the problems really are.

                That leaves trial and error...

                    AgentX20 Anyone had some or all of their wisdom teeth removed? Im checking possible TMJ connection with this. I think we must have something in common. Of course it can be genetic brain issue, but maybe not.

                        I have had my wisdom teeth removed, for sure. Martin, things I've considered:

                        • TMJ (I have mild TMJ and mild tinnitus, of the inflammatory variety... the muscles get swollen and it makes my ears ring and jaw ache, I sleep with a nightguard)
                        • Blue eye pigment (I am from scandinavian stock, but none of my siblings or parents have this issue)

                        All I know is that nothing definitively helps. I've had no eye problems on bad TMJ days, and vice versa. One thing that REALLY helps... is Lutein. I take a high-potency Lutein supplement and that is helping a LOT.

                        martin all wisdom teeth removed... At the age of 15. The light problems started 9 years later.

                            KM Yeah, my wisdom teeth came out at 19. Light problems started at 37. Not related, I'd say.

                                Gurm My wisdom teeth were removed at 19, my problems started at 18, am 21 now. So the light problems were before wisdom teeth removal (still had them).

                                  Ive been to a neurologist and the diagnostic is general migraine disorder. She said I can be happy I know the trigger (LEDs, flashing or color related) as some people have it from chocolate, red wine, weather..., and that there is nothing anyone can do about it at the moment. Gonna get an MRI soon but she said they probably wont find anything to catch onto, so just to rule out some physical trouble in the brain.
                                  Ive also been told that the typical inability to focus (on the screen or somewhere else) is a followup of the migraine already happening from something else (light).
                                  Maybe we are all just migraine affected people that came here because its triggered from the same thing - LEDs and flicker.

                                  Got a magnesium prescription as a nutrition supplement.

                                    ensete LED monitors use LED backlights. LEDs are extremely precise in reacting to input current, they turn off even for 1/100000 seconds(not that this would be a problem). Problems arrise for sensitive people when they turn of for 1/10000 of a second or more repeatedly.

                                    Just as not all LED light bulbs are alike so goes for LED monitors because of their backlight driver implementation. Just because it is marketed as flicker-free you don't have that guarantee. New cheaper LED drivers use integrated circuits which is not a bad thing BUT it does make the driver more sensitive to input current, so you might be lucky and live somewhere where you have good electricity and have no problems and some might not.

                                      I agree that migraines can also come from health issues BUT if you don't have a migraine and then you watch TV, play a game on a LED monitor or enter a room that is only lit by LED lighting(or CFL) AND you get a migraine or dizzy then it is not your gluten intolerance that is causing this. What next? Are you guys going to convince us the earth is flat? Or maybe the zodiac has something to do with the fact that you get a headache from invisible flicker?

                                      Please lets keep this as scientific as possible. There are a LOT of scientific papers regarding light flicker and invisible light flicker which causes a series of problems for humans and animals alike.

                                      If you would like I can provide links to some of those scientific papers. Until then you should read this article(use automatic translation from Chrome, does a pretty good job):

                                      Invisible flicker that is harmfull cannot be spoted even with a DSLR with 1/4000. Here is a toy that might help you spot it:

                                          martin Everybody is affected by invisible flicker. People like us either have better vision or we have eyes that are more sensitive to light flicker.

                                          All eyes get micro muscle contractions from light flicker, we are lucky that we also get headaches and we realize that something is wrong. You fix the invisible light flicker you loose the headache and you keep your 20/20 vision.

                                          Other people who don't get headaches don't care about this. They just loose their perfect 20/20 vision in a few years and think they lost it because they got older and not because of the light flicker.

                                              martin Genetic brain issue? You sound like you lost all hope!

                                              Not only there is hope but there are solutions. There are LED bulbs that don't give you headaches, monitors, smartphones etc.

                                              You just need the right tools to test these out. Subjective testing does not go a long way.
