Abstract

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.
