Abstract: Contact lens that, during use, creates a hollow space between its concave internal surface and the convex external surface of the eye and contacts the corneal epithelium only for a fraction of its internal surface facing toward the eye thanks to the presence of a plurality of micro-protuberances which allow to raise the contact lens by a few micrometers with respect to the corneal surface.

Abstract: The invention concerns a method to manufacture a mold (10) for forming contact lenses (100) using the technique of molding with molds of monomeric and/or polymeric material; such molds (10) comprise a male element (11) and a female element (12), which cooperate to define a cavity suitable to accommodate monomeric and/or polymeric material in the liquid state intended to form the lens (100), wherein the method provides to obtain, by means of laser processing, a plurality of grooves (23) in the male element (11) intended to form functional elements in relief (101) of the lenses (100). The invention also concerns a mold (10) for contact lenses (100) made of monomeric and/or polymeric material that can be obtained with the method as above.
