Abstract

Se describe un molde y un método para la produccion de una lente de contacto. Los moldes del invento permiten la formacion de una lente de contacto teniendo un borde sin rebaba mediante el uso de un mecanismo de enganche. El mecanismo de enganche evita todo, o substancialmente todo, el movimiento de lado a lado de la mitad de molde frontal en relacion a la mitad de molde posterior.A mold and a method for the production of a contact lens is described. The molds of the invention allow the formation of a contact lens having an edge without burr by the use of a hitch mechanism. The hitch mechanism prevents all, or substantially all, movement from side to side of the front mold half in relation to the rear mold half.
