A dropper tip 30 is provided which allows a person to instill a drop D into and eye E from a bottle 20 that has compressible and resilient walls 19 while the bottle 20 is held in a horizontal orientation.The dropper tip 30 includes an internal passage 37 into which a stem 35 is inserted. The stem 35 has a groove 36 along its peripheral surface which allows the flow of liquid 21 from the reservoir 20 to the free end 29 of the tip 30. The stem 35 protrudes from the external opening 44 of the internal passage 37 of the tip 30 and has a head 33 on the protruding end. The drop D adheres to the head 33 rather than adhere to and migrate along the external surface 28 of the tip 30.The dropper tip 30 further includes an annulus 32 at the free end 29 of the tip 30 which encircles the external opening 44 of the internal passage 37. The annulus provides a surface for a drop D of liquid 21 to adhere to while awaiting release.The dropper tip 30 further includes a fissure 34 at the free end 29 of the tip 30 which provides an area for drop formation and retention and also acts as a guide to direct the falling drop D into an eye E while the bottle 30 is held horizontally.
