Abstract

Perfil transversal de borde portante de lentes de contacto blandas y duras-blandas, caracterizado porque el borde de las lentes de contacto blandas o de las duras-blandas, así como el borde óptico de las mismas son gruesas, y porque en la mitad entre éstos dos bordes (análogamente al limbo del ojo), ambas superficies exteriores decrecen de tal manera una hacia la otra que el perfil transversal del borde portante en éste campo medio, campo del limbo, esté concebido de manera extremadamente delgada, facultativamente hasta alrededor de 95% más delgado que los espesores de los bordes o los espesores de los bordes ópticos, estando afilado en punta el borde exterior de las lentes de contacto blandas o duras-blandas, y las superficies interiores de éstas lentes de contacto blandas o duras-blandas se encuentren configuradas según una curva o varias curvas.
