Tear tape, also known as tearstrip or tear-off ribbon, is a narrow adhesive tape used to open packaging. The backing is often a narrow oriented polymer such as polypropylene but other polymers, yarns, and filaments are also used. Many tear tapes use a pressure sensitive adhesive but others have a heat-activated adhesive system.
A punctal plug, also known as tear duct plug or lacrimal plug, is a small medical device that is inserted into the tear duct (puncta) of an eye to block the duct. This prevents the drainage of liquid from the eye. They are used to treat dry eye. Artificial tears are usually still required after punctal plug insertion. [1]
Artificial tears are lubricating eye drops used to relieve dryness and irritation of the ocular surface. [1] Dry eye syndrome (keratoconjunctivitis sicca) is a common ocular surface disorder and is characterized by disruption of the tear film and increased inflammation.
Persons with dry eye conditions can be fitted with punctal plugs that seal the ducts to limit the amount of fluid drainage and retain moisture.

Despite the eyes being dry, those affected can still experience watering of the eyes, which is, in fact, a response to irritation caused by the original tear film deficiency. Lack of Meibomian gland secretion can mean that the tears are not enveloped in a hydrophobic film coat, leading to tears spilling onto the face.
