A blister package housing a contact lens is described. The package generally includes a base member including a cavity having a bottom surface, for containing a contact lens immersed in a liquid medium. The base member can include a grip region including a curved top surface shaped to accommodate a thumb and a curved bottom surface shaped to accommodate an inner curve of a forefinger. Silicone hydrogel contact lenses located in the liquid medium have a reduced tendency to stick to the bottom surface of the cavity without requiring a surfactant and/or a surface modification of the bottom surface.

La présente invention concerne un emballage en forme d~ampoule logeant une lentille de contact. L~emballage comprend en général un élément de base comprenant une cavité ayant une surface inférieure contenant une lentille de contact immergée dans un agent liquide. L~élément de base peut comprendre une région d~adhésion comprenant une surface supérieure incurvée prenant une forme permettant de loger un pouce et une surface inférieure incurvée prenant une forme permettant de loger la courbe intérieure d~un index. Les lentilles de contact en hydrogel de silicone situées dans l~agent liquide ont une tendance réduite à coller à la surface inférieure de la cavité sans qu~il soit nécessaire d~utiliser un agent de surface et/ou de modifier la surface inférieure.
