bike commuters who wear prescription glasses

[Filliam H. Muffman]

Rain-X can work wonders for the right car windshield but it needs to be really clean before applied. Rain-X relies on wind to clear the droplets. It does not work on my car at less than 35 mph and can actually reduce visibility in very light mist because the drops do not collect and blow off. I would only use it on glasses in the rain if I had a set dedicated for riding.
