This email came early last week and I decided to try it out before forwarding or posting it here.
"How to achieve good vision while driving during a heavy downpour. I can vouch for this!! We are not sure why it is so effective; just try this method when it rains heavily. This method was told by a police friend who had experienced and confirmed it. It is useful...even driving at night.
Most of the motorists would turn on HIGH or FASTEST SPEED of the wipers during heavy downpour, yet the visibility in front of the windscreen is still bad...... In the event you face such a situation, just put on your SUN GLASSES (any model will do), and it's a miracle!
All of a sudden, your visibility in front of your windshield is perfectly clear, as if there is no rain.
Make sure you always have a pair of SUN GLASSES in your car, as you are not only helping yourself to drive safely with good vision, but also might save a friend's life by giving him this idea."
As I left work on Friday, it began to rain. I turned on the wipers, but my vision was definitely hampered by the downpour. I remembered to try my sunglasses - and I was very surprised to see that they worked quite well - just as this email had said. I could leave the wipers on medium speed and see as well as if it was not raining at all. Next time you are in a heavy rain, put your sunglasses on and see it it helps you too!
