Yes the Ray Bans, SPY, and Costa Poly's, and Oakley have pretty much the same optical clarity. They are Base Prism lenses, most are In Mass Color, and also the coating for color, mirror, and scratch resistance are professionally optimized for clarity. That is typically the whole issue with aftermarket ones. There are no Base Prism aftermarket ones that I am aware of, and their coatings blur the clarity really bad.Really? So all of the above mentioned lenses have the same optical clarity? And you wear Costa's? Would've never guessed...
I am working on doing a series of SPY lenses, for custom cut X-Metals. To offer a different variety of colors, HOWEVER with the same optical clarity that is expected. Collectors and not wearing them will not be interested, but daily wearers will.
Well, For work I wear Tightrope SI, non and Polar, but usually other than that I wear the Costa Brine with green glass polar. Wore them to RED too. Just to be an ass. ( all a Joke) . I like the Juliets, and wear the Finito Carbon VR50's early morning and dusk times. The Violets occasionally (best optical colors for me), and a set of these. Theses are the best all around for Oakley lenses. Radar Blue Ir
