"Therefore my conlcusion so far is that I really do lack MPOD (macular pigment optical density) in my retina, and my retinas cannot filter out blue light." You should measure to have sure. So you can have sure, or else you could be mesguided. We have to be careful making conclusions, based on simple results. There are multiple variables.
I am thinking more and more, that the majority of problems are flickering related. But different kinds of flickering. Some dithering, color flickering, contrast flickering, etc. Some people are troubled by flickering on blue spectrum. So it's the photoreceptors either blue cones or RGPC's ganglion cells that are the sensitive. Maybe people have differente photo-receptors sensitivities. So for some people the blue light problems only occurs with flickering.
1- People only affected by flicklering.
2- People affected by flickering when blue spectrum is high. (different photo-receptors affected the number 1 group).
Do you have any LED display that dont cause you problems? Maybe on LED that dont have any substantial flicker of any sort?
