In summary blue light filters actually do work, through the indirect action of reducing overall light output, but the author has a larger axe to grind about the "technical details" (it's worth reading the article). The warmer color temperature reduces strain on my eyes, which I find both soothing and invaluable.
- MBCook 8mo agoThe author showed that Apple‘s implementation only cuts two colors by roughly 50%. And given we perceived light non-linearly aren’t they right that that really doesn’t make much of a difference? If someone put up an article saying “Turning down your headphones 1% will help stop hearing loss!“ most people are going to ignore it. OK yeah technically it will, but not to any meaningful amount.
- daneel_w 8mo agoSo which do you think it really is? Cutting two wavelengths' outputs in half, or reducing them by a mere 1% as per your trifling comparison?
