Abstract

En progressiv linse har et nærområde (RP) og et fjernområde (DP) med forskjellige styrker, samt et mellom område mellom de førnevnte områder med en gradvis styrkeovergang langs en meridian mellom disse områder, slik at det er et stort og stabilt nærområde (RP) og et relativt lite fjernområde (DP). Minst et av avstands- og nærområder er definert av et område med optisk stabilitet hvor styrken forandrer seg gradvis omkring og mot et punkt. Linsens progressive overflate fordeler dessuten overflateastigmatismen over hele linseoverflaten fra ovennevnte punkt i et område til ovennevnte punkt i et annet område. Serier av slike progressive linser for almen bruk, yrke og aktiv fritid omtales.
