I ended up putting the incandescent bulb back in and there were no more problems. I just turn the lamp off when I'm away from the desk or when I can see my reports clearly.
The problem is that our eyes are calibrated to the heat and wave length of sunlight. The eyes will adjust to less light, but as we get older they don't adjust as well. The cfl bulbs will work fine for back lighting or general room light, but for close work at a desk you need something like an Ott lamp to get adequate lighting. You still need decent back ground or fill lighting. A daylight spectrum lamp over a desk in a dark room is also bad for your eyes.
