Oh, agreed. I'm just saying that the "LED risk" being discussed is at worst of an order already seen by large existing workforces. So we office workers are at worst at a risk comparable to our farmer relatives. We should investigate and take what precautions are reasonable, but broadly: we can deal.

That makes sense; thanks for clarifying.

I do think the theory elsewhere in this thread about the different spectral distribution could be significant. This is why apparently non-UV blocking sunglasses can make UV damage worse: the pupils open wider when visible light is blocked and so let even more UV in. If you just skew the spectrum of some light source toward the UV without increasing the overall luminous intensity, presumably it could cause some health risks in a similar way.

Most decent household LEDs don't have significantly different spectra. Certainly nothing like what you see with CFL.
