Packaging for disposable soft contact lenses
The present disclosure provides a contact lens package containing a contact lens in a compressed state. In one exemplary embodiment, the overall internal depth of the package is less than the natural sagittal depth of the contact lens. Different single-use contact lens package shapes and configurations may be used. In some embodiments, a spring disc is included in the packages to help present the contact lens to the user when the package is opened. The contact lens packages may be adhered or clipped to a card or other carrier sheet, and may be housed in a number of different secondary packages.
1. A contact lens package manufactured with a contact lens therein, wherein the contact lens package deforms the contact lens, and wherein the package comprises two sheets of material sealed together, said sealed sheets each incorporating a non-permeable barrier layer defining a cavity, wherein said lens is disposed in said cavity; and
wherein a maximum internal depth between said barrier layers of said two sheets of material within said cavity is less than the natural sagittal depth of said contact lens.
2. The package of claim 1 , wherein each of the two sheets is flat.
3. The package of claim 1 , wherein the sheets pull apart to release the lens.
4. The package of claim 1 , wherein the sheets are sealed in an area surrounding the contact lens.
5. The package of claim 4 , wherein the seal around a perimeter of the package has an unsealed portion in at least one corner of the package.
6. The package of claim 1 , wherein the sheets are each multi-layer laminates.
7. The package of claim 1 , wherein the sheets comprise polyolefin.
8. The package of claim 1 , wherein a first barrier layer is a multi-layer laminate and said second barrier layer is polyolefin.
9. The package of claim 6 , wherein the multi-layer laminate comprises one or more materials selected from the group consisting of polyethylene terephthalate, polypropylene, and aluminum.
10. The package of claim 1 , wherein at least one of the sheets is embossed.
11. The contact lens package of claim 1 , wherein said two sheets of material sealed together further comprise a single sheet incorporating a non-permeable barrier layer folded back on itself.
12. A contact lens package manufactured with a contact lens therein, wherein the contact lens package deforms the contact lens, wherein the package comprises:
a first space defined by a non-transmissive barrier layer, said first space containing a hydration medium, wherein the lens is disposed in the first space;
wherein a maximum internal depth between said non-transmissive barrier layer defining said cavity is less than the natural sagittal depth of said contact lens.
13. A contact lens package manufactured with a contact lens therein, wherein the contact lens package deforms the contact lens, wherein said contact lens package comprises a retort-type package including a non-transmissive barrier layer defining a cavity, wherein said lens is disposed in said cavity, and wherein said contact lens package has a maximum height that is less than the natural sagittal depth of said contact lens.
