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 newly manufactured contact lens hermetically sealed therein, wherein said newly manufactured contact lens package is defined by at least one non-permeable barrier material, and wherein said at least one non-permeable barrier material directly contacts a surface of said newly manufactured contact lens and deforms said newly manufactured contact lens within the contact lens package.
2. The package of claim 1 , wherein the package comprises two flexible sheets of material sealed together; and
further comprising a free flowing hydrating solution hermetically sealed within said contact lens package with said newly manufactured contact lens.
3. The package of claim 2 , wherein each of the two flexible sheets is flat.
4. The package of claim 2 , wherein the two flexible sheets pull apart to release the contact lens.
5. The package of claim 1 , wherein said deformed contact lens is compressed within said contact lens package by said at least one non-permeable barrier material.
6. The package of claim 2 , wherein the sheets are sealed in an area surrounding said newly manufactured contact lens.
7. The package of claim 6 , wherein said sheets are not sealed on at least one corner of the contact lens package.
8. The package of claim 2 , wherein the sheets each comprise multilayer laminates.
9. The package of claim 1 , wherein the at least one non-permeable barrier material defines a first space containing a free-flowing hydration medium, wherein said contact lens is disposed in said first space.
10. The package of claim 2 , wherein at least one of the sheets is embossed.
11. The package of claim 1 , wherein said contact lens package comprises a retort-type package.
12. A single use contact lens package manufactured with a newly manufactured contact lens hermetically sealed therein, said newly manufactured contact lens having an anterior surface and a posterior surface;
wherein a relationship between the arcuate lengths of the anterior and posterior surfaces of said newly manufactured contact lens hermetically sealed in said contact lens package is altered from a relationship between the arcuate lengths of the anterior and posterior surfaces of said newly manufactured contact lens in its equilibrated state via engagement of said newly manufactured contact lens by direct contact to a non-permeable barrier material of said contact lens package.
