Multifocal Lenses provide two, or three distinct vision options. Bifocals provide a near, and distance vision field. Trifocals provide a near, intermediate and distance vision field. Both of these options have a visible line between the vision fields. Advancements have been made in recent years that give options to have different fields of vision without the traditional line. Check out our Progressive Lenses for a no-lined multifocal lens.
