Cavallier,
I called the UV Shield people to ask about their product. Their claims didn't seem very reasonable. Their website suggests that the film is colorless, but that it absorbs all light at 380 nm. That wavelength is visible to many people, and if that wavelength is absorbed, some 390 and 400 nm must also be absorbed. Those wavelengths correspond to blue light, and if blue is absorbed the film would be yellow. It turns out that the film does have a grayish tint to it to cover up the otherwise yellowish appearance, and so some visible light is absorbed (25%, 15% in CA). This product appears to absorb the 350-380 nm UV light better than most other window tint films, but this region of the spectrum is also the least harmful or damaging.
It seems like a reasonable product to try and that it fits your requirements (high UV, low visible absorption), but not quite as magic as the ads suggest. You can find a dealer by calling 800-447-8468.
I've got some info on the EX glass and it's UV-visible absorption. I'll post that later.
