Abstract
(EN) [Problem] To provide an eyeglass plastic lens which has antibacterial properties and in which the occurrence of an abnormal appearance is suppressed. [Solution] This eyeglass plastic lens 1 comprises: a plastic substrate 2; and a dielectric multilayer film 4 formed on a film formation surface M of the substrate 2. The dielectric multilayer film 4 includes one or more low-refractive-index dielectric layers 6, one or more high-refractive-index dielectric layers 8, and an antibacterial layer 10. The antibacterial layer 10 is a dielectric layer containing metal ion-carrying zeolite, and is disposed closer to the atmosphere side than all the low-refractive-index dielectric layers 6 and all the high-refractive-index dielectric layers 8. The physical film thickness of the antibacterial layer 10 is less than 50 nm.
(FR) Le problème décrit par la présente invention est de fournir une lentille de lunettes en plastique qui a des propriétés antibactériennes et dans laquelle l'apparition d'un aspect anormal est supprimée. La solution selon l'invention porte sur une lentille de lunettes en plastique 1 qui comprend : un substrat en plastique 2 ; et un film multicouche diélectrique 4 formé sur une surface de formation de film M du substrat 2. Le film multicouche diélectrique 4 comprend une ou plusieurs couches diélectriques à faible indice de réfraction 6, une ou plusieurs couches diélectriques à indice de réfraction élevé 8, et une couche antibactérienne 10. La couche antibactérienne 10 est une couche diélectrique contenant une zéolite porteuse d'ions métalliques, et est disposée plus près du côté atmosphère que toutes les couches diélectriques à faible indice de réfraction 6 et toutes les couches diélectriques à indice de réfraction élevé 8. L'épaisseur de film physique de la couche antibactérienne 10 est inférieure à 50 nm.
