I would be really interested to know and also what it could be an indication of.
For several years now I have had a real problem with bright fluroscent lights, to the point now where I go in shops I feel quite weird and disorientated.
At work I use uplighters and angelpoise lamp.
I never even used to be aware of lighting as I am sure most people are.
Could it just be general tiredness? Maybe an effect of spending so many hours on computer?
If anyone else has this please let me know and we could swap notes.
