Multifocal Lenses describe a collective group of lenses correcting two or more viewing distances. Bi-Focal lenses are lenses divided into two parts to correct any two prescriptions, most commonly close and long distance, but sometimes close and intermediate vision for reading and computer work only. These prescriptions are divided by a visible segment on the lens. Tri-Focal lenses work the same way, but correcting vision in three different distances with a small portion of intermediate segment added to the lens too. A more advanced and aesthetically pleasing multifocal lens design, also known as progressive design, has the ability not only to correct vision close and far away, but everything in between. These lenses are developed to shift the power across the lens without visible lines separating the zones or sudden change in power. Although the Bi-Focal and Tri-Focal lenses have their advantages, they are considered outdated and less and less popular, and the expression Multifocal Lenses is now often used as a synonym for Progressive Lenses.
