Abstract
There is provided a lacrimal fluid control device for blocking the flow of lacrimal fluid away from the surface of a wearer's eye through a punctal opening and into an associated caniculus. The lacrimal fluid control device includes a tip portion comprising a generally inverted truncated cone and a head portion comprising a generally enlarged dome. The tip is operable to facilitate placement of the lacrimal fluid control device at least partially through a wearer's punctal opening and the enlarged dome or head portion prevents drift of the lacrimal fluid control device completely through the punctal opening and into a generally vertical portion of an associated canaliculus.
