How to improve vision when driving in heavy rain

Well i got this forward mail about how you can improve road visibility when it is raining heavily. I find it rather strange to the solution that was provided, but i will try it out later when it rains heavily to confirm this.
The solution is pretty simple, you just need a pair of :

SUNGLASSES !!!!!

This is like something that we really never thought of using when driving in the rain, i am really surprised at it too ! Don’t really understand the logic of it as well, but i will definitely try it out, as sometimes it is really difficult to see the road when even the wipers are at full power during heavy rain.

Maybe that is why the F1 drivers can still drive properly even with their visors down during the rain, as the visor is also something like sunglasses.
