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 (9) or the placement of a divider (38) 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.

La présente invention concerne l'emballage ou la distribution de lentilles de contact hydrogels à l'état sec. Lors de l'emballage de lentilles de type hydrogel sèches, le risque de développement bactérien et de dégradation du produit ou de l'emballage habituellement lié aux lentilles humides est réduit, voire éliminé, allongeant ainsi considérablement la durée de vie du produit. Le fait d'appliquer un matériau (9) ou de placer un séparateur (38) entre les lentilles non humides empêche les phénomènes d'adhérences entre ces dernières et permet aux fabriquants d'emballer ces lentilles en augmentant l'espace efficace d'emballage. Ce système d'emballage et de distribution simplifie considérablement et réduit les coûts de la fabrication, du stockage, de l'emballage, des inventaires, et de la distribution des lentilles de contact de type hydrogel.
