The Maui Jim Readers work very well for me! Background: I'm a middle-aged woman who has worn off-the-shelf reading glasses for several years. I've just begun wearing prescription progressive lenses. I finally decided to purchase sunglasses with reading magnification for cycling because it has become increasingly difficult to see my bike computer over the past few years. I chose the Maui Jim brand because of their comfort and excellent visual clarity. I've worn Maui Jim sunglasses for many years and find them to be superior to the Revos and Vuarnets I used to wear. Please note: The manufacturer's description states that the bifocal is positioned to optimize distance views. This is very accurate. These glasses do not have the same large magnification area that progressive lenses have. It takes a short while to get used to finding the reading magnification "sweet spot." If you solely intend to use these glasses for reading on the beach, they may not be for you. On the other hand, if you intend to be more active when using these glasses, I think you will love them. They are perfect for reading your cell phone caller id, digital camera screens, iPod screens, sports watch timers and settings, etc. As for comfort and fit, they are extremely light weight, flexible and comfortable. The lenses are large enough to prevent wind induced tearing of your eyes while biking, but aren't too large. The frames sit on top of the head nicely and won't stretch out. If you have a very petite face, the frames might be too large. The Makaha model is for medium faces; the Ho'okipa model is for large faces. In my opinion, these are true unisex sunglasses, suitable for both men and women.
