Abstract A container or case for use in storing and sterilizing corrective contact lenses is made up of a shallow cup-like base, a cap for selectively closing the open end of the base, and a lens basket arrangement situated in the base. The lens basket arrangement includes individual lens pockets which have a central hub and spaced staves radiating from the hub, the staves including substantially coplanar inboard portions adjacent the hub and abruptly upturned outboard portions for confining a contact lens element within the respective pocket and against laterally slidably extraction therefrom.
