I see a thread from this time last year on this problem. I've been in touch with Jeff from www.safetyglassesusa.com. He's very knowledgable and suggest vented lenses, the anti-fog spray that they sell (supposed to be 3 times stronger than others), and foam-lined goggles/glasses. Oakley makes some vented lenses but they are pricey. Like others posted in last year's thread on this, my bike glasses fog when I stop in cold weather. They are OK when I'm moving, I guess because they are cooled by the wind on the outside or else there is enough air moving across the back side to keep the fog away. I'm tempted to try the oakley's here http://www.safetyglassesusa.com/oakl...ley-radar.html or here http://oakley.com/category/467, but I hate to pay that much.
Anyone have a solution? Cold weather riding is just around the corner.
