Oakley pioneered single-lens sports eyewear way back when in 1983, but they haven't released a markedly new cycling-focused design since 1990. Yes, the M-Frames were futuristic back then, but the style has been kind of ho-hum for years. It's still iconic, but is now conservative, when Oakley made its name being cutting-edge.
Like the M-Frame, the Radar a single-lens sunglass that is light, fits well, and has interchangeable lenses with great optics. But it does the old M's one up by employing a new hydrophobic coating on the lens. This coating makes it easier to see what's up the road when water hits the lens, as it just beads up and rolls off; the coating also makes it easier for dirt to come off, and harder for smudges to be seen because it's also oleophobic. The coating is transparent and permanent.
Another improvement over the old M is the nosepiece system. It's better in two ways. In terms of fit, Radars come with two nosepieces. One will fit better than the other; the come in different widths. This means it will sit properly on the schnoz, and neither pinch it nor sit so loose as to slide down. The second, more functional, improvement is that the nosepiece attaches to the rest of the frame. Oakley found that to meet military safety standards, the venerated M needed some decidedly garage tinkering. The new nosepiece attachment improves impact protection; it meets ANSI Z87.1 standard for both high mass and high-velocity impact resistance.
And then there are the surge ports. These are the holes molded into the arms. The ports direct air inside the arms so heat and sweat don't build up behind the sunglasses and arms. And unlike certain models of the M-Frame, the arms of the Radar fold. The lens is large in a modern, high-fashion way without being too big. We prefer the Path lens because we believe it is large enough to protect the eyes while being small enough so it doesn't overheat the head and seal the eyes off from the world. Overly big glasses fog up too easily. For those who are familiar with M-Frame lenses, this is kind of between the Hybrid and the Sweep. The next larger size of Radar lenses is the Pitch, and the largest is the Range. As with the M-Frame, the Radar has interchangeable lenses. Not only can you change tints, but shapes.
The White Chrome frame features a metal coating to the O-Matter frame made when the naked O-Matter is put in a vacuum with a metal chip. There is soft Unobtanium rubber on the ends of the temples and the nosepiece, same as the M-Frames. It's slightly hydrophilic, and grips better with perspiration. The lens is made from Plutonite (which blocks UVA, UVB, UVC, and blue light) has Oakley's famed High Definition Optics (HDO) for clarity and XYZ Optics for elimination of distortion. The lens color is Blue Iridium, which allows in 15% of visible light. It's best for medium to bright light and has excellent contrast. The Iridium helps cut down on glare. The sunglass comes with a zipper case that has room for a spare lens and a microfiber bag that is both a lens cleaning cloth and soft storage.
