TechOptica
Although "flicker-free" and "low blue light" LCD monitors are available on the market, the ones I have tried were not especially effective at reducing eye strain for me. I put together this monitor using incandescent backlighting and have been using it for half a year at time of posting. Quite comfortable for evening use, no further eyestrain symptoms, and even some improvement of eyesight.
Photos showing backside and "under the hood" are at the end of the video.
