I was thinking about my own helmet use the other day, particularly in
response to the helmet issue here in Ontario.
It occurred to me that helmet-wearing actually creates hazards for users
under certain circumstances.
For example, many times I have been blinded by sweat on fast descents when
air pressure squeeezes sweat out of the pads and into my eyes. The oily,
salty sweat causes near-total blindness for 3-10 seconds before the tear
ducts can flush them out. Knowing that the helmet will partially protect me
from the hazard it causes is not comforting. It's occured with every helmet
I have ever owned. It occurs frequently while riding around here. It is a
hilly area with lots of 6--12% grades.

You must be going amazingly fast if the air pressure squeezes the sweat out
of the pads. I've never had this problem going down hill.

Not sure about Mr Patton (the OP) but it does not take air pressure to
do this. I, as mentioned before have had it happen twice. Once was at
~ 70 km/h downhill and once on the flatat about 25 km/h. All it takes
is a hot humid day and time for the pads to absorb the moisture until
they are saturated. Then all you have to do is nod your head and
suddenly your eyes are flooded with extremely salty moisture.

You might also
try wearing a sweat band. That will keep the sweat out of your eyes.
