@Second_Coming The mechanism of blue light toxicity (415 ~ 455 nm) is well known, the retinol is excited and triggers an apoptosis path.
All is a question of proportion of the wavelength in the total light sensed by the pupil, which will let a constant amount into the eye by opening or closing accordingly.
So if you have a warm light in a Philips Hue LED, no problem, and most of whites in Philips Hue bulbs are OK too, as they are composed of many wavelengths.
However a simple LED like the side indicator of a FrameWork laptop is made of at most 3 primary LEDs colors, thus the blue wavelength gets a big proportion in a white color setting.
In the evening or in the night when there is no other light around, and your laptop is charging, your pupil is wide open.
As for the blue of the sky, actually it is 450 ~ 485 nm, so it is a bit different from the toxic blue (this distribution of the spectrum will have only a tiny fraction of its energy in the toxic zone. Picture a bell shaped curve centered around 467 nm and reaching 450 and 485 nm, and you see it will have only a tiny surface between 450 and 455 nm).
Ah and I forgot to mention, the above in the previous paragraph is because the sky blue spectrum is spread out, whereas the light emitted by a set of LEDs will be a group of discrete frequencies (“bars” instead of a smooth graph). So with a set of LEDs you get a huge lot of energy in each of those few discrete frequencies.
The biggest problem in the LED industry currently, health-wise, imho, is that the cheapest and most powerful blue LEDs have exactly the most toxic wavelength! And knowledge about it is not very common yet.
Maybe Philips Hue is more aware? I really don’t know. I’d say probably.
