One of the few time when it helps to have a windscreen, it deflects most of the water away from your glasses. Also, though some say carrying rain gear is bad "karma" I carry light nylon/coated 2 piece rain suit. Always ride with plenty of following distance and two fingers on the brake lever...less of a tendancy to GRAB which is a big NO-NO...a steady squeeze and as Hoop said more rear brake. Remember with good tread, you can still ride in the rain...just remember that just because racers can speed in the rain and lean the bike way over, it is not the same thing on the street where traffic conditions change rapidly.
