No one can put it better than Oakley themselves...
"The most demanding sport professionals in the world have fueled 30
years of Oakley innovation. Athletes have won more championships and
medals with our sunglasses than with any other single sport product on
earth. The heritage continues with Oakley RADAR, a milestone in
performance technology.
Maintains Sharp, Clear Vision:
Radar features Oakley Hydrophobic™, a permanent lens coating that
prevents rain and sweat from building up on the lens. It also repels
skin oils and other contaminates, so the lens is smudge resistant and
easy to keep clean. It even eliminates static electricity, so dirt and
dust particles won’t cling.
Stays Ahead Of The Sun:
Radar lets you change lenses in seconds to optimize vision in any sport
environment. Many performance lens colors are available, and all lenses
feature the unbeatable clarity of Oakley’s High Definition Optics®
(HDO®).
Offers A Secure, Custom Fit:
Choose the nosepiece that gives you the best fit – two sizes are
included with every frame. Like the stem sleeves, they’re made of
Unobtainium® to increase grip with perspiration. Oakley’s Three-Point
Fit optimizes comfort and holds the lenses in precise optical alignment
for superior clarity.
Optimizes Comfort, Protection and Clarity:
Radar is made of lightweight O Matter® for all-day comfort. To keep the
heat of competition from swamping you with sweat, the frame geometry
creates a cooling flow of air. Pure Plutonite® lens material filters out
100% of all UV, and Radar meets ANSI Z87.1 standards for impact
protection. The semi-rimless design means there’s no frame rim to block
downward view. Optical clarity exceeds ANSI Z87.1 standards, and
patented Polaric Ellipsoid™ geometry extends razor-sharp vision all the
way to the lens periphery."
