I haven't heard of that one, any links? I have heard of light sensitivity, in part because of the spikes in wavelength your pupils don't dilate as much and it takes them longer to "rebound". Sort of like looking at an eclipse directly, yours eyes think it isn't very bring but your still getting tons of IR and UV and that can get them a "sunburn" or worse so to speak. That could be a myth as well, but it sounds plausible anyway.

Also once the light bounces around it tends to smooth off those spikes, so yes I would think a lamp shade would help, or even a frosted glass cover. More importantly don’t stare at a CF or any light :) I say this as I stare at a computer montior...

A quick somewhat footnoted online discussion: (shall look for more proper references later)

I've seen other references elsewhere, but don't remember where offhand... The overall decrease in intensity from a lamp shade through diffusion (inser proper technical term here) of light is a bit different than what I was thinking of in terms of decreasing a specific wavelength peak, which would be a function of color of lamp shade (I would think, but don't know... thus the question...) One would assume that a lampshade of a given color would allow certain wavelengths to pass but not others, thus the resultant color, and perhaps some colors of lampshades would be protective against the presumed risk?

HUH!!
