I don’t really have an issue with ceiling lights, but I don’t see the point either.
Can be sitting in an office where basically an entire wall is windows, and someone will still put the lights on… why? There’s enough natural light.
Sometimes natural lights comes in at "uncomfortable" angles or simply leaves some corners relatively dark.
So the artificial light acts as a counter light to reduce shadows and create a more even lighting.
It's just taking nice blue-white natural light and pissing harsh yellow light all over it.
It makes me wonder if we have different amounts of blue cones, that they literally can't see all the blue light. Is there one of those colour blind tests that can estimate cone density?
Office lights tend to be a lot more blue than what's used in homes.
That's true. Office fluorescents are often a very clinical and harsh tone.
Maybe it's something to do with the breadth of the spectrum? Are some eyes better at utilizing a wife spectrum even if the intendity is lower, while other eyes care prinarily about the maximum intensity?
Or maybe it's something to do with exposure? Some people can't see the intensity difference between spill light from outside and dedicated room lights because their brain adjusts the effective exposure differently?
Maybe it's overexposure filtering. Some people get headaches from brighter light but don't notice the brightness because of all the extra work their visual cortex is doing to filter out the extra light, while other people genuinely need the extra intensity?
I'd be really surprised if people who have a neurological abnormality also happen to have a difference in eye anatomy, especially when the neurological anomaly is associated with other sensory processing issues. Occam's razor suggests that all the sensory processing issues NNT people have are a result of their brains being different.
There are individual differences in color perception.
Office blue light might be because blue light stimulates while red/yellow makes tired. But main reason is probably that neon tubes still are cheaper per square meter. Btw, selling them is now forbidden in europe, they are LED tubes now.
