Abstract

Un método para tratar una superficie de molde de lentes de contacto con luz ultravioleta para incrementar la humectabilidad de la superficie. Dichos moldes son útiles para fabricar lentes de contacto al disponer una mezcla de reacción entre un molde cóncavo de curva frontal y un molde convexo curvo de base antes de la polimerización. Al ajustar la humectabilidad de las superficies convexas y cóncavas, así como, la humectabilidad del saliente circundante, el desmolde de la lente de contacto resultante se controla mejor y los defectos se reducen.
