Abstract
An ophthalmic lens package comprises a shell having an internal cavity accessible through an opening in the shell and a drainage member that divides the internal chamber into an upper chamber and a lower chamber. The drainage member is permeable to aqueous liquids and is arranged to allow drainage of liquid from the upper chamber to the lower chamber. This arrangement of the ophthalmic lens package allows the consumer to retrieve the lens from the upper chamber without handling any significant amount of saline solution.
