The overhead lighting is commonly fluorescent and flickers at 120 or 100Hz (twice mains frequency) and beats against CRT refresh frequency. Many of us can see it directly, others just notice that they get headaches when they use CRTs. LCDs are not as bad in that regard, but they're still not perfect. Incandescent bulbs don't have this problem because they're primarily heaters and there's enough thermal lag to carry them through the dip in output ever 1/100th of a second.
There's also issues with screen brightness relative to the room but that problem is being inverted by the newer LCDs that are disturbingly bright compared to normal room lighting.
