Abstract
(EN)
A contact lens includes a body, having the plurality of monomers including at least some silicone monomer units including at least one zwitterionic distributed throughout the body. The contact lens includes a front surface and a back surface, where the silicone monomer including at least one zwitterionic group can be present in a greater concentration nearest the front surface than the back surface or a point therebetween. The contact lens can be formed by casting a polymer mixture containing the silicone monomer including at least one zwitterionic group.
(FR)
La présente invention concerne une lentille de contact comprenant un corps, ayant la pluralité de monomères comprenant au moins certains motifs monomères de silicone comprenant au moins un agent zwitterionique distribué à travers le corps. La lentille de contact comprend une surface avant et une surface arrière, le monomère de silicone comprenant au moins un groupe zwitterionique pouvant être présent en une concentration supérieure près de la surface avant par rapport à la surface arrière ou un point entre celles-ci. La lentille de contact peut être formée par coulage d'un mélange polymère contenant le monomère de silicone comprenant au moins un groupe zwitterionique.
