It seems as though there is no absolute when it comes to eyewear at speed. Unprotected, my eyes tear while teaching on beginner slopes (and no, I'm not doing the Mach 5 "Follow me!" progression
). While skiing at normal (or normal for some of us I guess) speeds, however, I've yet to find a sunglass that can keep my eyes from tearing.
Interestingly enough, certain brands or models of goggles don't keep my eyes from tearing either, so as I stated above I suspect our eyes have different tolerances when it comes to wind.
I know eye color can have an effect on the amount of sun one can handle w/out sunglasses (lighter colored eyes are generally more sensitive to light), I wonder if it can have an effect on tearing as well? I can't see how, but...? I also wonder if contact lenses change the equation, although I personally seem to discredit this theory, as I wear contacts yet am very sensitive to both sunlight and wind.
Thank god I'm still young enough to enjoy the routine of goggles down at 8:30 a.m., up as the lesson requires (student meet & greet as well as pertinent explanations, emotional exchanges (
, etc.), then back down until 4:00 or the bar, whichever occurs first!
