Abstract

A blister package for a contact lens is provided. A deformable slider supporting a lens is movable via pull-tab or hinge to lift the contact lens out of a lens well. The deformable slider can include a hinge connected to a flexible peel-away top of the blister package or connected to a pull tab that can be pulled to pull taut the deformable slider. A blister package is also provided that includes a hinged shell having a lateral opening opposite the hinge, and a deformable slider that is folded over onto itself and seals both a top chamber and a bottom chamber. By pulling a tongue of the deformable slider, which extends from the lateral opening, the deformable slider can be removed from the closed shell and the closed shell can be opened enabling access to the contact lens.
