Cosmetic contact lenses are designed to change the appearance of the eye. These lenses may also correct the vision, but some blurring or obstruction of vision may occur as a result of the color or design. In the United States, the FDA frequently calls non-corrective cosmetic contact lenses decorative contact lenses. Theatrical contact lenses are a type of cosmetic contact lens that are used primarily in the entertainment industry to make the eye appear unusual or unnatural in appearance.
