Should I try a different agent? A different lens material (mine is some kind of polycarbonate)?

I am a decades-long year-round, eyglass-wearing cycle-commuter in Boston, for a one-way distance of 14 miles to as low as 0° F. I've tried everything proposed in numerous threads to prevent dangerous fogging.

IMO forget the anti-fogging agents and (supposedly) well-sealed ski goggles, and opt for better-ventilated (and cheap) goggles as described in this post on the recent thread Cold Protection for Eyes…

The problems that I think are unique to cyclists, in comparison with cross country and downhill skiers, and snowmobilers is that when we ride we are breathing hard, as a cross-country skier might, but we encounter a faster oncoming wind to dissipate the moist exhalations.

Conversely, I'm pretty sure we are more forcefully exhaling a greater volume of warm moist air than downhill skiers and snowmobilers, but we do not necessarily share the faster oncoming wind effect, especially when going up hill with a further increased burden of exhaled warm moist air to disperse.
