Review on Bifocal Sunglasses by Style Eyes: A Perfect Blend of Style and Vision by Ryan Lindstrom

I bought these for cycling as I can't always make out the smaller numbers on the bike sat nav. They are not ideal for this application. Sunglasses sit too close to the face so they fog up when you stop. They also go all the way up to the crown of the head, so you can barely see underneath while riding. This makes it impossible to look down to see what gear I'm in or to look over my shoulder at oncoming traffic. If you're looking for something to play other sports on and still read your scorecard, these should work for this app. If you want to sit outside in the sun and read, they work for that too, but I would recommend prescription reading glasses. This forces your head into an uncomfortable position for prolonged reading.
