Progressive Eyeglass Lenses provide the smoothest transition from distance vision through intermediate vision to near vision, including all the in-between corrections as well. So the benefit is that instead of having just two different viewing zones (distant and reading) as in bifocals, your new progressive lens will have gradual progressive powers of correction (from top to bottom), this will ease eye strain and providing better vision.
Computer No-Line Lenses
Computer No-Line Lenses are an occupational progressive lens, a no-line multifocal that corrects near, intermediate and, to a degree, distance vision. It has a larger intermediate zone than regular progressive lenses, leaving less space for distance. Computer eyeglass lenses are generally not suitable for driving or regular wear.
