Abstract
This invention relates to the packaging or dispensing of hydrogel contact lenses in a dry state. By packaging hydrogel lenses dry, the risk of bacterial growth and package or product degradation commonly associated with hydrated lenses is reduced or eliminated, thereby significantly extending product shelf life. The application of a material or the placement of a divider between unhydrated lenses prevents the lenses from adhering to each other and allows manufacturers to package lenses in more space-efficient packaging. Such a packaging and dispensing system dramatically simplifies and reduces the cost of manufacturing, storing, packaging, inventorying, and distributing hydrogel contact lenses.
