ABSTRACT:
A blink-activated duct for supplying a solution to the eye of the user has a particular utility in introducing an artificial tear solution to the eye of those persons who are incapable of producing such a solution themselves. The duct consists of a reservoir section which contains the solution, and a pump section consisting of a contact lens or a Silastic tube assembly for delivering the solution directly to the eye. This pump section is activated by the eyelid compressing the contact lens or the Silastic tube assembly, causing the solution to be displaced to the eye and successively drawing additional solution from the reservoir section to the pump section due to the creation of a temporary vacuum.
