Eye Watering Experience !

[Lagotete]

I rode 900 miles this week end and found that the air circulation in the Justisimo was irregular. With all vent closed I could sometime feel warm and fine and sometimes there was a draft of air.
Result is that this morning I woke up with dry eyes and it took the all day to come back to normal. I am not asking for doctor advice to cure but for biker advice to prevent [img]style_emoticons/<#EMO_DIR#>/rolleyes.gif[/img]
I have always liked the idea of old style goggles but I would need to ride an Enfield or a Harley for that! Seriously, is is a Caberg Justisimo problem? Is there any technique to limit the problem?
