iover the past few years i started to find that the sweat in my yes was burning my eyes (and the goggles did nothing), so i purchased some sweat buster thing off of the internet:
http://www.traxfactory.com/ it worked ok.
hovever, i found for me and my melon that a sweat band from lululemon worked better. it is a little bit uncomfortable at first; however, i have gotten used to it and it keeps the sweat out of my eyes
i only wear mind when i am mtn biking as my effort level is way harder.
