ABSTRACT:
A contact lens cleaning and storage case includes a base having two container sections for holding a liquid; two lens holders, each positioned above a lower wall of a respective container section and each at least partially sitting within the respective container section, each lens holder having a bottom wall; a drain connected to the bottom of each lens holder for draining liquid from each lens holder to the container sections, the drain including reduced diameter openings for restricting a liquid flow rate so as to provide that liquid drainage from the lens holders to the container sections occurs in a time of ten to fifteen seconds; additional openings which provide fluid communication between atmosphere and the container sections so as to provide for displacement of air in the container sections; and two caps, each for removably covering a respective lens holder.
