Abstract
The invention provides contact lens packages in which removal of the lens is facilitated by providing a means for elevating the lens when the package is opened.
Claims2
A method for elevating a lens from a contact lens package, comprising the step of providing a package comprising
- (a) a cover having an inner surface;
- (b) a base and comprising at least two sidewalls and a bottom having an inner surface and wherein the sidewalls and base define a cavity;
- and
- (c) a ring extending downwardly from the inner surface of the cover, wherein, when the cover is intact and the package is sealed, the ring divides the cavity into a water-tight, inner cavity suitable for housing a contact lens and a solution and an outer cavity suitable for housing a foam capable of expansion upon wetting with lens storage solution;
- lifting the cover upwardly, wherein the contents of the inner cavity mix with the contents of the outer cavity so that the lens is upwardly elevated.
