How to get rid of rain on your visor when commuting

[H2O]

...not an answer, but a question.  I can't see Jack-shit after a while when commuting at slow speed in Cape Town's drizzle. Tried a product called "Rainclear" by Everon that's supposed to make the rain bead off, but it does not make a difference.
Anyone who can vouch for a product?
