Abstract

Det er beskrevet et apparat og en fremgangsmåte for å støpe en myk øyelinse bestående av en hann- og hunndel (10, 12), hvor det langs ytterkanten av den optiske overflaten til den ene delen (10,12) er en knlvkant (20) og det langs omkretsen til den andre delen (10, 12) er en kantbøssing plassert utenfor knivkanten (20). De to delene (10, 12) settes sammen slik at knivkanten (20) deformerbart penetrerer den andre delen (10, 12). Overskudd av prepolymer (16) støtes ut fra formhulrommet (14) og adskilles fra linsen i et diskontinuerlig område, definert av kantbøssingens (22) kontaktområde (18). Formdelen (10, 12) med kantbøs- singen (22) blir fremstilt ved å bruke en sylindrisk innsats og en ringformet hylse maskinert slik at den har kantbøssingen (22) på overflaten ved en ende.
