You've made this claim before, but it's impossible unless there was an underlying condition. If that was the case, any source of bright light would have caused it, not specifically LED bulbs. There's nothing inherently dangerous about LED light, please stop spreading misinformation.
I get that you don't like them, and I agree they can be annoying, but the magnitude of light needed to permanently damage otherwise healthy eyes only occurs in nuclear reaction.
The bolded part I quoted from you above is the only misinformation in this thread.
If you would like to be introduced to the person whose vision has been impaired I can introduce you. You are not a medical doctor and, even if you were, you have not examined the patient. He has a diagnosis from an ophthalmologist who has examined his eyes.
Do not twist my words. I did not say all LED light was inherently bad. I implied LED headlights were inherently dangerous. This implication is confirmed by at least one confirmed case of permanent vision impairment. I have never stated that all LED headlights will blind everyone who comes near them. However, they have definitely caused permanent injury to one person. I enjoy my vision and would like to keep it. I would also like my choice of headlight to not be the cause of another person's vision loss. In the spirit of helping my fellow man, I share an experience that, however uncommon, is real. If reading this can help even person avoid causing or experiencing permanent vision damage I will consider my effort well-spent.
You are welcome to walk onto any dealer lot with a 2024 model year car that has LED headlights, ask the salesman to turn the bright lights on, and kneel down in front of those headlights with your eyes wide open, and stare into that light as long as suits you. For best effect, you should position your eyes so that they are in line with the most intense light output. I would not choose to do this, but it is a free country and you are free to choose your own path.
