I've been using flux/redshift for a decade but I'm honestly not sure if I've noticed a difference in sleep quality on the occasional days when I've had it turned off.
For those that are really sensitive; nothing beats fl-41
Glasses. Used to have a massive migraine hit in 10 minutes exposure to fluorescent light.
Axon cover rx would push that to about 4 hours.
I have a few friends with high prescriptions and they report flux like tools at the least seem to reduce strain on their eyes and rehear eyes aren’t as tired at the end of the day.
Of course this might exist for some folks more than others similar to how ergonomic keyboards can appear help some more than others, while others aren’t affected by it at all.
> Experimental adult males were maintained in constant darkness (DD) or constant blue light (BL) with a peak emission of 460 nm produced by the MarsAqua Dimmable 165W LED Light with a photon flux density of 20–30 μmol/m2/sec (irradiance of ∼0.4 mW/cm2) measured at the level of horizontally placed narrow vials (Genesee Scientific), each containing 25 flies as previously described (Nash et al., 2019).
0.4 mW/cm^2 is 4 W/m^2.
If I understand the unit correctly, this is equivalent to sitting 50 cm away from a light source emitting ~12 Watt of blue light (50 cm radius results in a sphere of 3.14 square meters, 12 W / 3 m^2 = 4 W/m^2). Assuming a 40% efficiency, that would be a LED lamp rated at 20 W, and emitting only blue light.
Does this finding really translate to anything relevant for the human genome? I'm getting that vaporware sense..
"Blue light is bad for your sleep"
"Nah, turns out it doesn't matter, actually"
"No, now we're certain it's really bad, actually!"
