Wasn't sure about the bifocal sunglasses but I'm spending more time in Florida. So having the CliC always on feature, along with really nice bifocal, was worth the try. I wish there was a way to fold them up when not in use, but the vision, the look and the convenience can't be beat. Very, very happy and will buy more. Nitpick, but my wife thinks the frame/lenses are a bit small for my face but the Harrier Sun provided the most peripheral protection.
