Abstract

Se describen diseños de lente multifocal esférico imperfecto concéntrico que utilizan una combinacion de una superficie frontal esférica imperfecta, lo que resulta en reduccion de aberracion y mejoramiento de vision de contraste, junto con una superficie posterior multifocal concéntrica, para producir un diseño de lente que permite la vision clara a distancia y también cercana sin una pérdida de contraste que es generalmente típica de los diseños de lente multifocal concéntrico, de vision simultánea de la técnica anterior; la superficie esférica imperfecta mejora la funcion de transferencia de modulacion (MTF) de la combinacion lente ojo lo cual mejora el enfoque y contraste tanto de imágenes distantes como cercanas; la forma de diseño es válida para lentes de contacto y lentes intraoculares.
