I am a have sweater and given a hard effort in the right weather I can put out about 4 pounds of water per hour. I have always had trouble with sweat in my eyes and used to think that I just needed a better sweatband. But the real issue that I have is sweat from my face gets swept up into my eyes by the air circulation under my prescription glasses (I am severely near sighted). It is mostly sweat coming from below and/or just outside of my eyes. For me it is pretty bad as I end up having to 'wipe my eyes' (actually below and to the outside of my eyes) about every 45 seconds on a hot day. And interestingly it is far worse on the left side vs the right side.

I don't recall seeing this discussed and wondered if others also have this problem and how they handled it.
