Abstract

LA PRIMERA LENTE DE CONTACTO (1) SE SITUA EN EL OJO DOMINANTE Y CONSTA DE UN AREA CENTRAL ESFERICA (5) PARA LA VISION LEJANA, RODEADA POR UN AREA ANULAR NO ESFERICA (7) QUE POSEE UNA DIOPTRIA EN FORMA DE ADICION PROGRESIVA QUE VARIA DESDE UNA ADICION CERO EN LA PERIFERIA INTERNA HASTA UNA ADICION MAXIMA EN LA PERIFERIA EXTERNA, Y QUE PERMITE LA VISION A TODAS LAS DISTANCIAS, INCLUIDA LA LECTURA. LA SEGUNDA LENTE DE CONTACTO (3) SE SITUA EN EL OJO DOMINANTE. EL AREA CENTRAL (13) ES ESFERICA Y SE AJUSTA PARA LA LECTURA. EL AREA ANULAR NO ESFERICA (15) TIENE UNA REDUCCION PROGRESIVA DESDE UNA ADICION MAXIMA HASTA UNA ADICION CERO, LO QUE PERMITE LA VISION QUE VA DESDE LA LECTURA A LA VISION INTERMEDIA Y LEJANA. ESTE SISTEMA PERMITE EN LA MAYORIA DE LOS CASOS UNA VISION DEL 95-100 % A TODAS LAS DISTANCIAS.
