The at least one lever surface is configured to provide at least one leverage point for movement of the applicator cap relative to the container.
Claims27
A device for storage and application of a contact lens, the device comprising:
- an applicator cap comprising a handle portion having a first end, a second end, and a body that extends between the first end and the second end, wherein the body comprises at least one lever surface;
- and
- a container having a reservoir configured to house a contact lens and packaging solution,
- wherein the at least one lever surface is configured to provide at least one leverage point for movement of the applicator cap relative to the container, and
- wherein the at least one lever surface is a rotational lever configured to rotate the applicator cap about a central axis of the container in a first direction.
A method of applying a contact lens to a wearer's eye the contact lens stored in a package comprising an applicator cap comprising a handle portion having a first end, a second end, and a body that extends between the first end and the second end, wherein the body comprises at least one lever surface, wherein the at least one lever surface is a rotational lever configured to rotate the applicator cap about a central axis of a container in a first direction;
- and a container having a reservoir configured to house a contact lens and packaging solution, wherein the at least one lever surface is configured to provide at least one leverage point for movement of the applicator cap relative to the container, and wherein the second end is configured to form a seal against a convex surface of the contact lens, the method comprising:
- rotating the handle portion with the leverage point about the central axis of the container;
- breaking the seal between the convex surface of the contact lens and the second end of the applicator cap;
- removing a contact lens from the convex surface;
- and
- applying the contact lens to the wearer's eye.
A method of packaging a contact lens, comprising:
- providing packaging solution in a container;
- providing a cap with a convex surface that is sealable with the container, wherein the cap comprises a handle portion having a body that includes at least one lever surface, wherein the at least one lever surface is a rotational lever configured to rotate the cap about a central axis of the container;
- providing a contact lens in a convex up orientation in the convex surface forming a seal between the convex surface of the cap and a concave surface of the contact lens;
- and
- sealing the container by pressing the cap to the container.
