The present invention involves an eye drop dispenser attachment having a cannula tip that can provide a consistent dose of medication. The attachment includes a base portion, a neck portion, and a tip portion. The base portion can contain threads for removable attachment to a bottle. The attachment can also include a protective covering for surrounding the tip to prevent injury to a user. The attachment can further include a cap that can be removably attached to either the base portion or the neck portion. The attachment can be incorporated into a bottle assembly or it can be screwed onto an existing bottle. The tip preferably has dimensions consistent with current ophthalmic cannula technology in the range of 20-40 gauge depending on the size of drop desired. An alternate embodiment of the attachment can be slidably disposed on the end of a traditional bulb-type eye dropper.
