The article didn't say everyone became ill but that some do. Put me in that "some" group. I can't stand to be around those lights. They make me edgy and give me a headache. Yes, I noticed it decades ago and would turn off the lights and just use sunlight at work. Present day, kids and I told hubby not to buy them but he did and put them in the kitchen. We ripped them out the first night.
I have the same issue, they really throw me off.
I can deal with them if there are other light sources (sunlight, regular bulbs) in the room, but straight fluorescent, I can’t deal with them....
