Abstract
A blister package for a contact lens is provided and has a body and a seal. The body includes a handle and a deformable bowl. The seal seals the deformable bowl at a bowl top opening. The handle includes a lateral portion and an end portion. The end portion curves downwardly to a distal end that terminates at a plane. The bowl is recessed from a top surface of the body and the outer bottom surface of the bowl is arranged substantially on the same plane as the distal end of the handle. The design provides leverage in holding the blister package while a user deforms and inverts the bowl into a dome, presenting a contact lens on top of the dome in position for direct transfer to a person's finger or for application directly on an eye without the need for any finger contact.
