There have been a number of threads about glasses, googles, face shields, etc. I had corneal edema in my left eye at the WTTC in Borrego Springs. It was caused by the cold air overnight. Since them I've been trying different goggles and face shields. The one I found works best is Kroops Boogie goggles. They are designed for horse jockeys (Kroops has a similar product with a different head strap for sky divers). They are flexible, so the fit is excellent. My first test was on my MTB when the air temperature was 45F. My eyes never teared up at all, and the goggles didn't fog up until I was climbing a steep hill at ~5mph. Next test was on my V20. I did get a little bit of tearing when descending at 38mph when the temperature was 48F. And the goggles fogged a little when climbing at 7mph. I switched from the goggles to my Oakley glasses on the way back. The difference was dramatic. My eyes were tearing on and off the entire way back, and the lowest temperature was 54F.
