Dear qbsbrown,
I had this symptom, too, and I'm going to venture a guess based on a study done on DPed people. PET studies were done of the brains of several DPed people by, I believe, Daphne Simeon, a couple of years ago. They seemed to show "hyperperfusion" or too much activity in DPed and DRed patient's parietal lobes. This is the second most important area of the brain in processing vision. First your visual images go to your occipital lobe in the back of your head, then the flat image travels to the parietal lobe where spatial recognition occurs, the awareness of your body's position in this space, and finally 3 dimensional vision. If this area is over or under excited, you may either lose your 3 dimensional vision, and get the flat "DR" look, or you may experience a stimulation overload from bright colors or lights. The particular properties of fluorescent lights make your brain's neurons very vulnerable to overstimulation. When a neuroligist does an EEG, fluorescent lights are often used to induce a semi-seizure, because they have this peculiar quality. Television also can induce seizures pretty easily, and I'll venture a guess that most people on here feel worse for being on the computer or television for long periods of time. I'll eventually get this all down in a DP paper I'm writing. Unfortunately, I sent an email to Daphne Simeon for input, and still no reply. I'm afraid that she may not be as up to date with neurologic developments as I once thought. Irregardless, using sunglasses seems to be pretty good advice, and I would think that an anticonvulsant might help as well. Eventually, however, it may subside on its own. Neuroligists have also found that low-grade seizure activity will respond to coping techniques used for anxiety, so thats a thought as well.
Peace
