It's time to take it backstage. Please give a warm welcome to Porgy Backstage. With full, clear magnification lenses. See what you're eating in the green room. As you hear the crowd behind the velvet curtains. Two dot detail. Top of frames engraved with "Goofy" and "Regular." From indoor venue to the outdoor festival. CADDIS progressives are for people who need to see stuff up close and far away. It's that simple. Our lenses progress from no magnification at the top, to your chosen magnification at the bottom. All in one lens. No more switching glasses stacked on your head. CADDIS Progressives are true progressive lenses (not blended bi-focals). As with any progressive lens, you may need up to a week for your eye to adjust to them. Be patient friends, the results are worth it.
