A molded blister package for storing and dispensing a hydrophilic contact lens comprises a base portion which includes a cavity surrounded by a outstanding flange, and a cover sheet sealed to the flange to enclose the cavity. A portion of the side wall of the cavity is inclined to form a ramp to the flange. The cover sheet may be stripped from the flange to expose the cavity and inclined side wall whereupon the lens is readily removed by sliding up and out of the cavity along the inclined surface.
