As you noted, perhaps the rapid eye movement may
contribute to CH in some cases. However, I wonder
if you have considered this:
1) Light emission from the screen
2) Type of radiation being emited by the CRT (older
CRT's may have some pretty harmful levels of UV, and other
spectra of light that might be damaging)
3) Ozone emission form PC/CRT
4) Flickering of the CRT (older models may be worse)
Since we as CH sufferers all report sesitivity to light,
perhaps the CRT might be part of the equation. Do
you have a radiation/glare filter screen on CRT? These
are rather inexpensive, yet very effective. There is nothing
that can be done about the flickering other than changing
the CRT. The flickering is perhaps inperceptible to
the human eye, but look at it after taping it with a video
camera. Although the veriations in light intensity might be
immediately inperceptible, perhaps the constant
variation may have an effect.
Just a few thoughts
Happy to c u back :)
