Abstract

La présente invention aborde le problème de la fourniture d'un ensemble d'articles optiques à transmission ophtalmique capable d'améliorer le contraste visuel dans la vision binoculaire et de ne pas altérer le confort. Un ensemble d'articles optiques de transmission ophtalmique de la présente invention comprend deux articles optiques de transmission ophtalmique, les longueurs d'onde montrant la transmittance minimale parmi les valeurs minimales de transmittance dans la région de lumière visible des deux articles optiques de transmission ophtalmique étant différentes l'une de l'autre, une différence de longueur d'onde entre les deux articles optiques de transmission ophtalmique étant de 35 nm ou moins, et les longueurs d'onde des deux articles optiques de transmission ophtalmique étant situées dans la plage de longueurs d'onde de 560 à 605 nm.
