- Contact lenses are not the only solution here. The use of a helmet
- with a face shield will make sure that the rain drops occurs only on
- the outside of the screen. The use of an anti-wetting agent such as
- Rain-X will ensure that water is kept to small beads which quickly
- fall off. And the use of either a handy chamois leather, or the old
- biker's trick of chamois patches sewn to the back of the first finger
- of the gloves (you can buy gloves like this), can wipe them clean very
- quickly.
-
- I don't mention goggles because when cycling in cold rain there is the
- fogging problem; a simple visor avoids this.
-
- By far the best solution to this problem, the rotate-in-the-wind
- turbovisor, is alas no longer made. It worked amazingly well, but
- wearing a spinning visor was too much for the very fashion-conscious
- cycling world :-)
