Multifocal Progressive: Multifocal lenses also provide a more natural correction of presbyopia than bifocal or trifocal glasses. Instead of providing just two or three lens powers like bifocals or trifocals, progressive lenses are true "multifocal" lenses that provide a seamless progression of many lens powers for all viewing distances.Progressive lenses have no dividing lines as they are in bifocals or trifocals. With Multifocal lenses, you can look up to see clearly across the room and in the distance. You can also look ahead to view your computer in the intermediate zone and drop your gaze downward to read and do fine work comfortably. And Multifocal lenses eliminate an annoying problem caused by bifocal and trifocal lenses known as "image jump." With conventional bifocals and trifocals, images seem to "jump" as your eyes move past the sharply defined boundary between the distance and near parts of the lens. With Multifocal lenses, the transition between lens powers within the lens is smooth and seamless, letting you change focus from distance to near and back again more comfortably.
