The packages described by this invention all have reduced 'head space,' that is, the distance from lid to lens. Packages contain dimples to achieve this reduced head space. Specifically, packages are designed with dimple sag equal to or less than 1.90-mm, or volume displaced equal to or less than 360 &#x3bc;l. Combined with the existing primary packaging, it has been found that such conditions provide for reduction in folded lens rate during shipping and handling. As well, lenses stored or having an extended time in low head space packages in a 'foil down' orientation now have characteristics closer lenses stored in a &#x201c;foil up orientation&#x201d;.

Contact lens package with reduced head space

The present invention describes single-piece or multi-piece Rigid Inserts that may be included in an Ophthalmic Lenses or may comprise the Ophthalmic Lens, wherein the Rigid Insert may be formed through the processing of thin sheet material by thermoforming. Single piece annular Rigid Inserts may perform the function of providing a template for printed patterns to be included in Ophthalmic Lenses. Single piece full Rigid Inserts may perform the function of polarizing light or filtering light based on the properties of materials used to form the insert. Multi-piece Rigid Inserts may include activation and energization elements. The present invention also includes methods and apparatus for forming the Rigid Inserts.

The present invention describes methods for creating single-piece or multi-piece Rigid Inserts that may be included in an Ophthalmic Lenses or may comprise the Ophthalmic Lens, wherein the Rigid Insert may be formed through the processing of thin sheet material by thermoforming. Single piece annular Rigid Inserts may perform the function of providing a template for printed patterns to be included in Ophthalmic Lenses. Single piece full Rigid Inserts may perform the function of polarizing light or filtering light based on the properties of materials used to form the insert. Multi-piece Rigid Inserts may incorporate activation and energization elements. The present invention also includes apparatus for implementing such methods, as well as Ophthalmic Lenses and inserts formed with the Rigid Insert pieces that have been thermoformed.
