Abstract

A contact lens applicator film ( 45 ) for picking up a contact lens ( 11 ) and applying the contact lens to an eye comprising: a sterilised film ( 45 ) wherein at least a portion of at least one side of the film comprises an adhesive coating that is arranged for adhering to the surface of a finger such that, in use, when applying the contact lens to the eye a user can pick up the contact lens applicator film with the finger and subsequently pick up the contact lens using the finger protected by the contact lens applicator film.

First claim

The invention claimed is:

1. A storage container for contact lenses comprising:
at least one well for receiving a contact lens and a storage liquid, the well having a floor;
a support structure for holding the contact lens in a defined location above the floor of the well, the defined location comprising a lens depression area that in use permits depression of the contact lens under finger pressure, wherein the support structure comprises a plurality of spaced apart fins extending from one or more walls of the well; and
a guide capable of engaging a contact lens edge when the contact lens is inserted into the well and to urge the contact lens to lie within the defined location and over the lens depression area.

2. The storage container of claim 1 , wherein the lens depression area comprises an unsupported portion of the support structure and the guide urges the contact lens centrally over the lens depression area.

3. The storage container of claim 1 , wherein each of the plurality of spaced apart fins cooperate to comprise the guide.

4. The storage container of claim 1 , wherein each of the plurality of spaced apart fins comprises a first profile for supporting a concave surface of the contact lens and a second profile for guiding the contact lens over the lens depression area, and wherein the first profile allows the contact lens to deform about a fulcrum when finger pressure is applied to a portion of the contact lens in the lens depression area.

5. The storage container of claim 4 , where the first profile extends between the fulcrum and the guide such that a distance between a point on the guide and the fulcrum is less than or equal to a length of the contact lens that is in contact with the first profile.

6. The storage container of claim 4 , wherein each of the plurality of spaced apart fins comprises a third profile adjacent the fulcrum that engages with an underside of the contact lens when the contact lens is depressed in the lens depression area.

7. The storage container of claim 1 , further comprising:
at least one contact lens applicator film for picking up the contact lens and applying the contact lens to an eye, the at least one contact lens applicator film comprising:
a sterilised film; wherein at least a portion of at least one side of the contact lens applicator film comprises an adhesive coating that is arranged for adhering to a surface of a finger such that, in use, when applying the contact lens to the eye a user can pick up the contact lens applicator film with the finger and subsequently pick up the contact lens using the finger protected by the contact lens applicator film.
