Abstract
Abstract A colored contact lens having a very natural appearance is disclosed. The inventive lens has a non-opaque pupil section and iris section that is at least partially opaque and comprised of two portions. A first portion, generally located on the outside of the iris section, has a first shade. A second portion, generally located on the inside of the iris section has a second shade. A jagged border separates the two portions. A third iris section and second jagged border are also disclosed. In some embodiments portions of the iris section may be non-opaque.
