I have never tried it but I believe it really works!
If you are driving during a heavy downpour, how do you maintain good vision? The tip bVisual Courtesy:elow apparently works and is even effective in night driving.
During a downpour, we all turn our wipers; yet the visibility in front of the windshield is sub-optimal.
In such a situation, just wear your SUN GLASSES!
Voilà! The visibility in front of your windshield is perfectly clear, as if there is no rain.
Try it for yourself and share it with your near and dear ones. Amazingly, you will still see the drops on the windshield, but not the sheet of rain falling. The sun glasses work to eliminate the “blindness” from passing cars spraying on your car, too.
