With annual 150 inches of rain, Gray days, I find 'Shooter' Yellow glasses work really well I have found the two pair on eBay used. They serve well as driving glasses at night against the on coming headlights.
(After posting this, and looking myself, for yet another pair of shooting glasses, came across this article which is contradictory to what my experience has been. However as it is written by a eye related publication, I offer it as we all enjoy this thread.)
