One of the many beauties of the Oakley Radar is the ease with which you can swap out its lenses. Oakley makes the perfect lens for any light condition, so by owning a few sets of lenses you'll be ready for any circumstance.
Removing an Oakley Radar lens is a piece of cake: With two fingers carefully pinch the nose bridge tabs inward. Then push the nose bridge towards the top of the sunglasses until the lens releases from the top. You can then pull the lens down and out.
Installing the lens is even easier: Just insert the tab on the right side so it's fully seated. Arc the lens outward slightly to insert the left lens tab. Then pull the top of the frame over the top of the lens while pushing the lens inward with both thumbs. When the frame is completely over the top of the lens, push the nose bridge forward so it snaps into place. Simple as can be.
One additional note: No matter what size Radar lens you current own (Path, Pitch, or Range), you can swap your current lens out for any other size. We only offer the Path size 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. And 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 Clear lens is an ideal choice for night riding, or a race in a downpour, or riding in otherwise dim-and-dismal conditions and you're not so much worried about blocking light as you are protecting your beloved eyeballs. If you've spent only 5 minutes of your life on a group ride, one truth has already been made clear to you: Debris flying around at head level is a fact of life when you ride with others. Neglecting to wear glasses makes about as much sense as leaving your helmet in the car.
The Black Iridium lens is a superb choice for the spring and summertime. It transmits only 10% 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.
The Blue Iridium lens transmits 15% of the available light. It utilizes a VR28 lens tint whose purpose is to further tune contrast and reduce glare in comparison to Black Iridium.
The G40 lens transmits 40% of available light, ideal for days of variable light -- anywhere from partly cloudy to overcast days, for example, when you need something that on the one hand can amplify the available light, but on the other hand won't have you squinting when the sun is bright.
The VR28 Black Iridium lens is a glare-cutting wonder. Iridium filters out blue light to increase contrast and improve depth perception in almost any set of conditions. In this VR28 option you get 18% light transmission, which is ideal for medium-to-bright light. It gives just a bit more transmission than the Blue Iridium.
Persimmon is the best choice for flat-to-low light -- we're thinking fall and wintertime here. It transmits 59% of available light, and its Iridium coating filters blue light to boost contrast and enhance depth perception.
All Oakley Radar Path replacement lenses are made from Plutonite to provide you with superior comfort, clarity, and protection against impact and ultraviolet radiation. Plutonite blocks 100% of all UVA, UVB, UVC and harmful blue light.
