Pst kid, you want to see some confirmation bias?
Admittedly, I do have a bias here, which has been developed through personal experiences with LED technologies. The first experience that I can remember was with LED flashlights years ago. No one wanted one of those things pointed at their eyes. The reaction to LED flashlights was much stronger than with traditional filament flashlights. The light from them was intense, very blue, and had lots of glare. The same was true with LED headlights. When those things came around, everyone complained about seeing them on the road. It was uncomfortable to the eyes and blinding to everything else on the road when those things were coming at you in the opposite lane. Then I got a laptop using LED backlighting, coming from a laptop that used a CFL backlit display and a desktop that used a CRT monitor. I never had any issues with the latter, other than sometimes getting red and dry eyes from the CRT after spending long hours in front of it. But within a year or two of using the LED backlit display, I got a wicked case of eye strain that physically made me feel sick, with aching eyes and feeling like I had the flu. I never had eye strain before that point, so I didn't really understand what was going on. After that, I got more cases of eye fatigue, but having experienced full-on eye strain, I knew enough to get away from the display before eye strain set in. As the years rolled on, I began seeing lots of mentions of blue-light and PWM eye hazards related to LED displays. And LED lighting became mainstream, followed by lots of people talking about feeling uncomfortable with LED lighting and potential hazards of LED lighting. At some point it began to be more difficult and more expensive to find the same range of incandescent/halogen bulbs (and CFL bulbs looked bad to me), and I decided to try LED lighting at home. But I still haven't found LED lighting that I feel comfortable with for reading and other tasks. It seems ok for me in less critical areas, such as hallways and porches. So yes, I do have a bias from these personal experiences with LED technologies. But I am still willing to explore newer LED technologies to see if there is something out there which might work for me, because LED lighting has obvious benefits of power efficiency and potentially lower cost over time.
