Oakley Radar EV vs. RadarLock vs. Radar
The Oakley Radar and RadarLock are extremely similar; the main difference between the two is the RadarLock is a little easier to interchange lenses with Oakley's SwitchLock technology. Also, for the non-prescription wearers, the Oakley RadarLock automatically comes with two sets of lenses: one color for lower-light conditions and one color for sunnier conditions.
The new Oakley Radar EV does not come in a SwitchLock version yet, (we'll let you know if and when it does!) and that's okay. Changing out the lenses is pretty simple. Here's a video tutorial on how to change the Radar EV lenses.
So What's the Difference between the Radar EV and the Original Radars?
Improved Upper Frame Design: Oakley improved the upper peripheral design on the new Radar EV, so the glasses sit a little higher up on your face. For those of you looking for some great cycling glasses, this means the top of the frame is not obstructing your vision while you're leaning forward in the cycling position.
More Unobtanium! Unobtanium is Oakley's rubberized material that increases grip the hotter you get and the more you sweat, keeping your sunglasses optically aligned and in place. The Unobtanium on the radar EV extends from the ear socks to the rest of the inside of the temples, so there's more grip action than the older Radar models. All three models still have the same unobtanium nose pads.
Improved Anti-Fog Venting On the Oakley Radar EV, the venting on the side of the temple is closer to your face, creating a more effective anti-fog mechanism. The venting on the top of the lens is also improved.
"Taller" Lenses The deepest (or tallest) part of the lens on the Radar and Radarlock is 42mm, while the Radar EV is 46mm. That's an extra four millimeters of lens coverage! Also, the lenses on the Radar EV Path have a more dramatic sweep design, giving them a more ergonomic angle above your cheek bones.
