Abstract

Se describen moldes para lentes de contacto y sistemas y metodos para producir moldes de lentes de contacto. Las secciones de molde para lentes de contacto incluyen dos superficies con calidad optica, una brida que circunscribe al menos una porcion de las dos superficies con calidad optica y un miembro alargado que se extiende desde la brida. Dos secciones de molde pueden contactar entre si para formar un montaje de molde que tiene un actividad con forma de lente de contacto. Las secciones de molde se estructuran para formar un lente de contacto que tiene un borde que no requiere mayor modificacion fisica antes de colocar en un ojo. Se describen sistemas y metodos que dirigen un material polimerico fundido a cavidades que corresponden a las secciones de molde.
