Abstract
Contact lenses that comprise a multi-layer design may be utilized to enhance and/or highlight the appearance of the eyes upon which the contact lenses are positioned while maintaining a natural look. These exemplary designs each comprise three layers; namely, a unique limbal design graphic, a unique inner effect graphic and a unique outer effect graphic. The layers may be formed utilizing any number of design elements and design principles. The limbal design graphic is the portion of the overall pattern that surrounds the outer diameter of the iris and is closest to the sclera and is meant to highlight, enhance and/or define the limbal region of the eye; however, it also comprises elements that extend into the iris. The inner effect graphic layer is the portion of the overall pattern that is meant to enhance the iris; however, it may comprise a portion that also contributes to highlighting, enhancing and/or defining the limbal region of the eye. The outer effect graphic layer is the portion of the overall pattern that is meant to enhance the iris; however, it may comprise a portion that also contributes to highlighting, enhancing and/or defining the limbal region of the eye.
