The Unspoken Dangers of LED Lighting
It has failed because despite the fact that most people around the world find LED car headlights and other LED outdoor lights unbearable, the scientific authorities involved in LED and laser optics and lighting have not convincingly demonstrated that LED lighting is harmful.
Subsequently authorities like NHTSA (National Highway Transportation Safety Authority) and FDA (Federal Drug Agency) in the USA and their counterparts in Europe and other continents and countries have embraced LED lighting claiming there is no proof that LED lighting is harmful.
After having a prominent career in the field of optics, optoelectronics, semiconductors, and fiber-optic communication technologies where I have extensively published in peer-reviewed journals and even wrote a textbook on LED illumination that is used by University of Mumbai and other notable universities around the world, I had a horrendous time publishing the science that explains why LED lighting is harmful to us.
The peer-reviewed journals’ editors-in-chief just would not let such publication pass through citing the reviewers found my work invalid. No matter how many times I presented rebuttals against the erroneous reviews from some peer-reviewers, there were more erroneous reviews that appeared.
All my rebuttals against these peer-reviews can be found in my ResearchGate profile although there is no guarantee that such articles will always be available to the general public. [1]
Eventually I managed to publish the science and mathematics behind why LED illumination produced by flat, inorganic LEDs is a radiation pattern that is not only strange; but it is indeed radically different form the illumination produced by the sun, the candle and the type of artificial light previously used before LED lighting came along. [2]
I did not mention the danger of LED lighting directly in this paper published in the IEEE Photonics Journal in 2019. I knew if I mentioned it, I risked the chance of publishing this work. But I hinted in this paper that the luminance or brightness values from LED chips and LED arrays are off the chart and would cause harm for vision.
I used calculus and physics in this work that is similar to authentic Bharatiya ganita and physics that were all but ostracized by the British colonizers in India. [3] It was the beginning of my journey to dig further into Aryabhata’s calculus and other mathematics that all originated in India.
If one could learn such ganita that used to be taught in India before Macaulay, one would soon recognize that LED lighting’s harm has nothing to do with blue light and has everything to do with using a flat radiator, which our sun or any star is not!
For such ganita that explains that the culprit is not the wavelength or frequency of light – but rather the geometry of the light source, it is imperative to learn what Gauss’ Law says and how to do calculus in various curved coordinate systems.
But alas – it turns out that just like Newton did not fully understand calculus or the laws of motion described by Kanad, Gauss too did not understand Gauss Law that happens to be the first of the four Maxwell’s Equations.
The list of what all European mathematicians and scientists missed about calculus and physics is a very long one. [4] Recently, there are others who are speaking out against LED lighting. But while they are right about certain conclusions, their scientific understandings around a point radiation source, coherence, the role of quasi-monochromatic light emission of LEDs and lasers, frequency modulation and why LEDs are actually harmful for us are vastly incorrect. [5]
To correct such claims, we need a serious effort in bringing Bharatiya ganita and science back. Hopefully we can achieve such by effective collaboration amongst us.
Interested readers are encouraged to watch my latest podcast on the dangers of LED lighting where I mention how Surya Siddhanta helps in developing the right science and mathematics for good and bad illumination from various light sources. [6]

Will blindness eventually be a result?

Yes – blindness or near blindness including color-blindness will all occur for most people eventually. It has already started for the older population to some degree. The degradation is slow and it is hard to notice that LED headlights and other outdoor LED lights are the culprit; with not only extremely high luminance along the center optical axis, but the light distribution in space-time is also neurologically harmful.
