Not careful?

well i have been playing with my x105, always use my goggles when doing close up burning, but when pointing on white wall I look away, but afterwards i get tired in my eyes, just like welding blind(trying to translate from Icelandic) but a lot less effective, does this damage my eyes bit by bit or do they recover from this after each time? you know i don't feel horribly but i can feel that my eyes are tired..

I'm pretty sure its too bright like walking outside after being inside for awhile.


Kinda like when your eyes hurt as soon as you walk out.

Hmm, I experience the same sometimes.
Looking at the spot (especially when its dark) creates something like flashblindness.

But I really don't know if this is harmfull if this happens too often.(I hope not)
