Marek,

UV-light can cause irritation (or "burning") of the skin at 
intensities far below what can be detected by UV-sensitive markers. 
It's just a matter of how long you are exposed to it.
Maybe you could try a good "sun-block" cream (the ones you use when 
going to the beach in summer) on you face.
If it is UV that causes the rash: glass blocks UV rather effective. It 
would stop teh UV while still allowing visual control of the coil.

73,
