I’ve been researching eyewear before I blow ~$100 on a piece of plastic that goes over my eyes which supposedly 1) doesn’t let UV-A,B,C through 2) polarizes light so, for example, snow won’t be so reflective 3) distorts the imagery as little a possible (“optically perfect”) and 4) also doesn’t break easily or obstruct field of view. The first two are pretty obvious (but are all of the glasses that polarize doing it the same way when they don’t all seem to be the same color or transparency?).
My main question is how does one gauge or measure this “optical perfection” that all of these companies are claiming. For example, one of them makes the claim that a technology called “Polaric Ellipsoid” allows their eyewear to distort light less than any other company’s, though I could find no literature or objective testing even explaining what their term means. The claims by different manufacturers are never ending, and I couldn’t find any objective optics sources to scrutinize them scientifically. Some claim that their polycarbonate lenses are as good as it gets, while others claim that polycarbonate is not a good lens material. Are these just marketing techniques under the facade of science? How can one ‘benchmark’ these types of optics (for “optical perfection” and such)? Thanks for the input.
