Technical Examples

A package (10+20+30) for contact lenses (10), especially 'daily-disposable' lenses, in which the overall volume of the package and the internal volumes of the lens-holding cavities (20) in the package are minimised. The packages are preferably multi-cavity packages, with each cavity holding a single lens and all the lenses being inserted into their respective cavities with a common orientation such that a wearer of the contact lenses has the assurance that a lens can always be retrieved from a cavity in a standard orientation. The internal surface (24) of a cavity preferably deviates from sphericity by being formed with undulations (50) to break capillary attraction between the lens and the cavity wall (24) so aiding extraction of the lens from the cavity. On the instructions of an ophthalmic practitioner, packages of suitable lenses can be made up and dispatched by courier or by post to wearer of the lenses.
