Ophthalmic products come in a variety of package formats and have a variety of eye-care applications. The liquid filled package formats are often soft containers with snap on or torque screw caps, but also include foil lidded blister packs for single use contacts. Most contact lens solutions clean, disinfect, lubricate, and remove protein deposits from the lens while matching certain chemical properties of the ocular area. While these solutions may disinfect, similar properties to ocular fluids and increasing resilience of new bacterial and fungal strains make contamination a greater concern. Any breach, channel, or micro leak in the container closure greatly increases the risk of contamination of the ophthalmic solution.
