The Jet Black frame offers full-on fashion versatility -- no matter what you wear, Jet Black is the perfect match. But what sets this model apart from the rest of its Radar brethren is its lens technology. Oakley has long spread the gospel about their Black Iridium lenses: It's a superb choice for the spring and summertime since it transmits only a fraction of the available light to your eyes, making it ideal for bright, sunny days. The Iridium coating creates a uniform filtering layer that optimizes contrast and reduces glare. In addition, these lenses are Polarized, which cuts glare even further in comparison to a standard Iridium lens. No Radar lens transmits less light than the Black Iridium Polarized -- only 9% of the light comes through. On bright days, this is your best bet.The Radar is Oakley's first new cycling-specific design since the M-Frame -- that's a 15-year span between re-designs, testament to just how popular the M-Frame became.

I will never buy sunglasses from Oakley again. Not worth the money. I should mention that I bought the Sunglasses from Oakley's main online site located in southern California. As mentioned, when new they're great. They just don't last.
