A bifocal contact lens is provided having a posterior surface that is formed to fit a human cornea and an anterior surface. The bifocal contact lens has an upper portion and a lower portion when viewed in a planar view. The anterior surface includes a distance vision surface and a near vision surface. The distance vision surface is substantially semicircular in form and located in the upper portion of the bifocal lens. A near vision surface is disposed within the lower portion of the bifocal contact lens and also surrounds the distance vision surface. |
