Abstract
This invention pertains to an apparatus for a drug delivery system to administer topical ophthalmic drug preparations. The apparatus relates to an optical gauging assembly which, when combined with or coupled to any standard topical ophthalmic drug dispensing unit, enables the user to view a target, visually align the dispenser tip, and administer an eye drop with precision. There is also a visual mechanism by which the dispenser tip is prevented from gaining too close proximity and contacting the eye, thus preventing contamination of the medication and its dispenser.
