Black Forever Progressive Eyeglasses feature two fields of view in each lens, seamlessly blended together for a smooth look with no distracting lines between the different fields. These Black Forever Rx Glasses feature stylish frames based in a wide range of retro looks, each with a modern twist and present-day sensibility. If you want some serious style in your glasses, get yourself a pair of Black Forever Progressive Bifocals. These line-free bifocals feature an amazing width and breath of style, achieved purely through the shapes and cuts of the frames. Black Forever Progressive Glasses include bold, chunky plastic frame designs for those seeking a true "downtown" look, as well as thinner, modified rectangles and cat eye shapes, squares featuring black crystals, and larger styles ideal for the hip and the youth-minded.
