Bifocals all work in the same way. A small portion in the lower part of the lens contains the power required to correct your near vision. The rest of the lens is for your distance vision.

The lens segment (or “seg”) devoted to near-vision correction can be one of several shapes:

  • A half-moon — also called a flat-top, straight-top or D segment
  • A round segment
  • A narrow rectangular area, known as a ribbon segment
  • The full bottom half of a bifocal lens, called the Franklin, Executive or E style

Generally, you look up and through the distance portion of the lens when focusing on points farther away, and you look down and through the bifocal segment of the lens when focusing on reading material or objects within 18 inches of your eyes.
