Hey guys,
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 bright 3) represents light as my eyes usually perceive it ("optically perfect"). The first two are pretty obvious (but are all of the lenses that polarize doing it the same way? 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" all of these companies are claiming. Naturally, I was looking at Oakley eyewear, and they seem to have made up a term without really defining it or (seemingly) allowing anyone to investigate it (as I could not find the term in any literature searches): Polaric Ellipsoid (they claim this gives them clearity closer to perfection than any other manufacturer). A couple of their other buzzwords are: Unobtainium, Earsock, Plutonite, XYZ Optics, O Matter, X Metal, Earstem, and Nosebomb. Are these just marketing techniques under the facade of science? How does someone without lots of time and lab resources get to the bottom of this ridiculous marketing? Which glasses are the most "optically perfect" and how can one determine this? Thanks.
