Found some great pilot's bifocal sunglasses while in the fishing store (Bass Pro) -I-GOGS.
What makes them great is that the bifocal portion is clear glass (no tint or polarization). That means that when you look up, you have polarized sunglasses, when you look down, you have non-polarized, non-darkened, close magnification. These were designed for fishermen so that when they look down at their GPS units, they can see them clearly. Often these are hard to see because of the polarized interference.
Works great for us in the cockpit too!!
Available in sport stores, list $20.00.
