On my Android phone, you can use night-light which just changes the spectrum of photons that hit your eye. The theory is pretty simple -- since lower wavelength photons have less energy than higher wavelength photons, the radiation ends up having less destructive potential. I would consider that an improvement.
- textor 8y agoThat's not it at all and nobody cares about "destructive potential" of screen-emitted photons, though. The actual reasoning behind shift to lower wavelengths is that our circadian rhythms are entrained by ambient light, with "blue" light being assumed as indicative of daytime and "red" tones – of sunset (ergo, time to ramp up melatonin secretion and prepare to sleep).
- anonytrary 8y ago> That's not it at all and nobody cares FYI - macular degeneration and circadian rhythm disruption are not mutually exclusive, and lots of people try avoid both of these things...
- ferongr 8y agoBut is there actually any scientific proof of something like this? The studies on the effects of blue light concern way different levels of luminous output.
