    A simple polarizing film should just reduce the incoming light, which one could compensate for. I don't see why it would produce a colorcast since all it is doing is polarizing the light. Humans, and...

    Good point, about it needing to be googles. Since laser light can be refracted, etc... one would need protection from above, below, the side, from behind, etc... and only a google can provide that.

    This sums it up. I've seen it both ways. Some docs are like "Why are you bothering me with this crap?" and some, if you do it yourself, are like "Why did you feel you could go ahead and do that for...

    Excellent advice, for life in general. If it's a fire larger than a match, you generally can't "blow" it out. All one does at that point is provide a pressurized stream of 16% oxygen to said fire.

    Have you tried a trial frame? If he sees it through that, something else is going on. If it's not present, it indeed appears he is unusually sensitive to the optical properties of certain materials.
