100% UV blocking dark grey polarized sunglasses combined with a handy +2.50 power bifocal segment in the bottom of the lens (the top portion has no prescription). The temples are wide for extra sun protection and contain a unique see through side shield to help with peripheral vision (the side shield is not polarized). Perfect for fishing--cutting the glare from the water's surface yet allowing you to see up close to tie your knots and read your charts. Or while driving, you'll be able to see the instrument panel, maps, etc. The bifocal portion of these glasses is nonpolarized (but still tinted), allowing you to see liquid crystal displays (your fish finder, the display on the gas pump at the gas station, etc.). You'll wonder how you ever got along without them!
