Abstract

Questa lente ha una superficie asferica (S) presentante una zona (VL) per la visione lontana, una zona (VP) per la visione vicina e, fra questo due zone, una zona (VI) per la visione intermedia, con una curva meridiana (MM') lungo la quale la curvatura della superficie varia progressivamente e che è inclinata dall'alto al basso verso il lato nasale della lente almeno nella zona (VI). La parte (DP) della curva mediana situata nella zona (VI e VP) è divisa in un segmento (VC) formante con la verticale un angolo o il cui valore è funzione crescente dell'aggiunta di potenza A della lente, e in un segmento (CP) formante con la verticale un angolo più piccolo di . Nel punto (C), alla giunzione dei due segmenti, la superficie (S) ha un valore di sfera media che corrisponde ad un'aggiunta di potenza compresa tra 0,8 e 0,92 volte l'aggiunta nominale di potenza della lente.Fig. 1
