Rain gets in my eyes, err, on my glasses...

Even here in sunny SoCal we get rain from time to time (and we seem to be into our weeend pattern lately). As one who wears glasses and finds himself out in the rain occasionally, I have had to deal with obscured vision. My response to the falling wet stuff has always be to pull my trusty cycling cap lower. That takes care of most of the drops, but has little effect against road spray. So, it was with interest that I read through this post from BikePortland.org; might as well go to the experts for advice, and who is more knowledgeable about riding in the rain than our two-wheeled brethren up north.
