It's near red infrared. It's like saying that blasting red light to your face, will have health consequences.

That is simply not true.

For example: There are, in fact, known risks to near-infrared radiation exposure. Erythema ab igne, for example, is a disorder characterized by a patchy discoloration of the skin and other clinical symptoms. It is caused by prolonged exposure to hearth fires, and it is an occupational hazard of glass blowers and bakers exposed to furnaces and hot ovens (e.g., Tsai and Hamblin 2017). It is not a risk to the general population, however, in that the irradiance is usually many times that of solar near-infrared irradiance.

There's a huge difference between shining a few 30mA IR diodes in your face versus working all day in front of an open furnace.

I never said it is the same as open furnace. I just said that there is a distinct lack of health considerations around this idea. And your commend really underlines my statement. I mean, IR is not visible and if I can't see it, it can't hurt me, right? :-D

But seriously: She has 22 IR LEDs. Let's say 50mW each and you have over 1W of illumination in there. If you wore it while outside/at work, it could easily add up to 10 hours a day, 6 days a week. That's really not "nothing", even though the immediate intensity is not comparable to furnace, the overall dosage very well might be...

I have IR burnt streaks running over both my corneas from working near an airfield in the 80s. Those are from diodes, or perhaps tubes.

Apparently it does, positive ones!

Yeah in "normal amounts" - basically what body expects from the sun. :)

I have not calculated the power output of those LEDs, I merely pointed out the fact that I don't think healt consequences should be completely overlooked by just saying "meh, it's like red, no worries"...

Does your face feel warm, when the sun shines on it? Would it feel warm from a handful of low power IR LEDs? I doubt it. People underestimate the power of sunshine.
