These lenses are maximized for the computer or your near and intermediate work area. They may be as simple as a single vision Blue Light filtering lens, a bifocal, or the latest office progressive. These new lenses maximize an area for a larger monitor while also having a small near portion at the bottom for near reading, and even a strip of distance for part time viewing far away. Multiple coating options are available. These are often the happiest pair of glasses you will ever get!
