I don't think that this is the reason.
Yes, there is something obviously wrong with most LED lights, but it isn't too much of short wavelength light, but on the contrary. It's the near absence of cyan light in most LEDs. Our eyes are by far the most sensitive to it, the majority of receptors in the eye are sensitive to it, and we may focus primarily on it (focus differs for different wavelengths). This is how you get the feeling of something being wrong with your vision as you for example walk into a mall, and so on.
If anything, higher temperature lights seem to make it better, not worse, but the problem will persist as long as the cyan hole stays there.
- guenthert 9mo agoSensitivity peak for humans is in cyan (~510nm) only for low-light conditions (night vision / rod cells). In daylight (cone cells) it's green-yellow (555nm). https://www.giangrandi.ch/optics/eye/eye.shtml https://www.giangrandi.ch/optics/eye/eye.shtml
- accidentallfact 9mo ago>The eye behaves differently in high or low light conditions: in daylight, for brightness levels above 3 cd/m2 the vision is mainly done by the centre of the retina, we can see colors and the maximum sensitivity is at 555 nm (in the green region). This type of vision is called photopic vision. That's completely impossible, you would have severe tunnel vision in daylight, if it was true. There has never been any real evidence that rods stop working in daylight.

I think it's illegal to drive with less than 20°FoV. https://www.google.com/search?client=ms-android-samsung-rvo1&hs=bIu9&sca_esv=6a0b219675808712&udm=2&fbs=ADc_l-aN0CWEZBOHjofHoaMMDiKpaEWjvZ2Py1XXV8d8KvlI3lB6BRmAv9Tdx4SvL4ZREsvAtO7uvBzcA2nI7Y2smQuOcOD1BRIJlYEP9L184wHplUnDJZldrEB9OrnQhro058BtHQi8SjOi7hgEVYTYNC4yFp6wV67XyBoBwgLNG_K6icd74SWNfqaojX3OWwqk_7UYMP03hPB86wRBy18I_YUyr-l_mg&q=cone+density&sa=X&ved=2ahUKEwijtcO2oKuSAxWfgP0HHYQhNR8QtKgLegQIEhAB&biw=411&bih=747&dpr=2.63&aic=0#sv=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_LfECDABSgoIARACGAIgAigC https://www.google.com/search?client=ms-android-samsung-rvo1...
