Lentes Progresivos
Lentes Progresivas: también conocidas como Lentes de Adición Progresiva (PAL), Lentes Multifocales y/o Bifocales Sin Línea.
Las lentes progresivas proporcionan tres campos de visión en una sola lente con una progresión perfecta y natural en la potencia en toda el área de visualización.
Comenzando con su potencia de distancia (lejos) en la parte superior, aumentando lentamente y gradualmente en potencia, hasta que se alcanza la potencia de lectura completa (cerca) en la parte inferior.
Una lente progresiva ofrece una visión clara de lejos a cerca y toda la distancia en el medio.
