I just want to remind everyone that LED backlights emit blue light that isn't eliminated by f.lux or similar utilities.

- mediaman 8y agoCan you explain this more? If LED backlights emit multispectrum light (to get a white), and the LCD display filters those spectrum via RGB selection (say, letting less blue through, and more red/green), wouldn't this effectively filter the blue spectrum? I know very little about this so I'm genuinely curious.

- herf 8y agoYou might want to refer to our measurement project for some numbers: https://fluxometer.com/rainbow/ https://fluxometer.com/rainbow/ Also, you can be below threshold for circadian responses just by being very dim.
- hohenheim 8y agoLooking at your measurement, if I understand it correctly, you are saying that OP is incorrect and flux does in fact reduce the blue light?
- abledon 8y agoSo if a new macbook pro has: "15.4-inch (diagonal) LED-backlit display with IPS technology; 2880-by-1800 native resolution at 220 pixels per inch with support for millions of colours" What possible laptop alternatives are out there that are better for eyes?
