Ensures functionality of all mechanisms of firearms.Short and mid-term anticorrosive protection.Fit for all types of firearms – sport firearms, pistols, and short guns, rimfire rifles, hunting and long-range rifles, automatic rifles, military weapons systems and all parts of weapon metal accessories. Polarization has nothing to do with reducing reflected light so I would expect that if that study also used polarized lenses in addition to tinted lenses the reflectance curves would look virtually the same (allowing for the variations for the material type and lens quality) when comparing similar tint colors individually.GUNSHIELD™ CLP® is a new generation of cleaning, lubricating and preservative solution for complex gun maintenance. Remember polarizing filters only allows light through a single plane (in the case of ophthalmic polarized filters it would be the plane of light that is visible to the human eye). Now with polarized lenses I would not expect a significant difference in reflected UV vs. So, I'd be interested to see if they repeated the study with Purecoat and Super HiVision EX3 vs Avance UV or Sapphire UV whether the results would be as bad as that generation of coatings due to the decrease in reflectance that we're seeing in the current generation of ARCs vs that generation of ARCs (I'm separating the Crizal coatings vs non Crizal coatings because if Crizal's claims are independently verified then I would expect that there would be a statistically significant difference between Purecoat or EX3 and Crizal Avance UV in reflected UV). But what I found interesting in the study was that ARCs performed worst than the uncoated lenses as a side note the paper was published in 2008 so the ARCs tested were Zeiss's Teflon and Gold (Zeiss Gold on the 1.9 Glass that was tested), Crizal Alize, Hoya High Vision, and Polycore's Mxplus (which I have never heard of and while Polycore does list an ARC on their website it is just called Anti Reflective Coating). The paper studies clear lenses coated with ARC or not coated with ARC and tinted lenses but not polarized lenses. I found Essilor's white paper, but then I looked at the studies they cite to see where they are supporting their UV reflectance claim and that would be the paper: Anti-reflective coatings reflect ultraviolet radiation from the Journal of Optometry the full text is available here.
