> Compare your acuity in outdoor, shaded light, to a solely fluorescent lit environment The amount of light in the shade outdoors, or on an overcast day, is around 12 EV [1]. A bright indoors office with fluorescent lights is around 8EV. This means that the human eye will be receiving 16 times more light in the outdoor shade, compared to even a bright indoors room. That's a big difference that has nothing to do with the source of the light. Common sense also dictates that fluorescent lights did not get popular in homes until the last 10 years due to the rise of CFLs, and yet kids grown up in the 1970s have increased myopia rates- the source of the myopia therefore cannot be due to the indoor lights.
