发明名称 A process for manufacturing colored contact lenses.
摘要 <p>A process for manufacturing colored contact lenses, and the lenses obtained by the process, based esentially in the discovery that it is possible to apply the colorant (11) (or color layers) to the convex (12) or concave face (17) of the manufacturing mold in such a way that the desired iris imprint is later infiltrated into the lens till final embodiment next to the selected surface. The resulting cosmetic contact lens has a transparent pupil section and a colored annular region whose structure, covering entirely the user's iris, conceals it partially by means of a screen that contours conveniently the visible pigmented layers of the human iris, chromatically intermingling with the pattern of said iris. This lens is capable of modifying the perceptible iris color of the user, while retaining a natural appearance, even under almost near vision onlooker gaze.</p>
