Contact lens packaging and methods

A contact lens package, comprising blister packaging defining a cavity, a contact lens disposed in an unstressed state within the cavity, lens hydrating liquid partially filling the cavity, and lid stock sealed to the blister packaging such that a segment of the lid stock, in combination with the cavity, forms an enclosure of the lens and the liquid. The segment has an interior surface including at least one relief element. The interior surface exclusive of the at least one relief element is flat. An air gap is disposed between a top surface of the liquid and at least a portion of the interior surface. The at least one relief element on the interior surface of the lid stock may be formed while testing the structure for leaks by applying pressure to the lid stock with a stamp having a contour corresponding to the at least one relief element.
