Abstract

Det tilveiebringes et linse-formhulrom som så evakueres ved hjelp av en vakuumkanal i et formelement. En fluidumventil åpnes for derved å åpne linse-formhulrommet for innføring av et flytende linsemateriale. Undertrykket i linse-formhulrommet vil trekke det flytende linsemateriale inn for fylle linse- formhulrommet. Fluidumventilen blir så lukket og det flytende :linsemateriale i linse-formhulrommet blir herdet for oppnåelse av en oyenlinse, såsom en kontaktlinse.
