Abstract
Procédé de durcissement de lentilles ophthalmiques ou d'ébauches semi-finies de lentilles, selon lequel une résine durcissable est tout d'abord exposée à un rayonnement dans une plage de longueur d'onde comprise entre 400 et 800 nm avant d'être soumise à un traitement thermique ou à un rayonnement de longueur d'onde ou d'intensité différente de celle appliquée pour la première étape. Cette résine polymérisable renferme de préférence: (1) un premier photo-amorceur qui est activé par un rayonnement d'une longueur d'onde située dans la plage des 400 à 800 nm et (2) un déclencheur thermique qui est activé par la chaleur, ou bien un deuxième photo-amorceur qui est activé par un rayonnement d'une longueur d'onde ou d'une intensité différente de celle utilisée pour activer le premier photo-amorçeur.
