Why is every professional location so brightly lit, and do most people not get headaches and fatigue from it?

i've turned down schools and jobs just for this reason, i just can't work in these extremely bright lights without getting headaches and fatigue that makes it so i cant really go further about my day as usual.

i think i might have a bit of a higher intolerance than the usual person, but am i really the only one who works worse under these lights? why are they even so bright in the first place?
