Oh, the Photofusion is kind of like having an automatic transmission in your car. It is just for you, you don't worry about it, you don't think about it, you just turn the ignition and drive and go. Right now ZEISS is kind of like...they got it. They are so much better than what I've worn before. I have a girlfriend and every time the sun comes out she puts on her sunglasses. When she wants to read she puts on her reading glasses, when she wants to drive at night she puts on her driving glasses. That would drive me crazy. So with this one pair of glasses, they save me a lot of money, they make my life easier, they reduce my stress and they‘re just very natural to wear. I don‘t even notice that I have them on.
