the inverted eye drop dispenser comes as an integrated part of the eye drop bottle package.it is made ready by unscrewing the eye guard piece from the bottleneck, turning it around and threading it back on to the bottle.when placed against the edges of the eye socket, the guard attachment stabilizes and aligns the bottle prior to squeezing and dispensing the drops.this reduces the possibility of misplaced drops and wasted medication.when finished, the eye guard can be unscrewed, flipped around and threaded back on the bottleneck, where it compactly nests against the form of the eye drop bottle and closes the bottle with a fliptop cap.
