Herein, the background art relating to the present invention is provided, and they are not necessarily referred to as known arts.

In general, tears are supplied from the lacrimal gland to the eyeball surface to moisturize the eyeballs. The blinking action of the eyelids causes the tears to lubricate and remove foreign substances from the eyeballs.

Human tears flow into the shallow pool, known as the lacrimal lake, which is secreted by the lacrimal gland, across the surface of the eye, where the eyelids are located at their inner ends.

From there, tears are drained through small openings in the respective upper eyelids and lower eyelids, called superior lacrimal punctum and inferior lacrimal punctum, respectively.

From the upper and lower points, the tears enter the upper and lower canal tubes, respectively, which are duct-type passages leading to lacrimal sac.

On the other hand, in patients with dry eye syndrome, the surface of the eye becomes dry because the tears are supplied to the eye in an excessively small amount.

Such ocular dryness can not be accomplished by lubrication and removal of foreign substances using tears. Therefore, when the eyelids are blinking, the eye becomes sick and the eye is always kept in a state of blood redemption. A tear point plug was used.

However, according to the conventional art, there is a problem that the eye dropper may continuously irritate the eyeball even when the eye dropper 10 is properly inserted into the fistula 21, causing pain in the eyeball 20.

The cause of the pain is that when the lower lacrimal puncture point, i.e., the lower lacrimal tube 21a is located in the inner or inner position of the eyelid, the inserted lacrimal puncture plug 10 stimulates the eyeball 20, .

In addition, when the tear point stopper 10 is provided on the upper eyelid tear point, that is, the upper nozzle tube 21b, the head portion 13 protruding toward the eyeball continuously irritates the eyeball surface, causing pain.
