Eye drops are a must for those of you who have dry, itchy eyes. Although it makes the eyes more comfortable, not a few people who complain of throat feeling bitter when swallowing after using eye drops. How could that be?
Why does the throat feel bitter when using eye drops?
Naturally, if you feel bitter shortly after taking oral medication. However, what if you are not taking oral medication? But eye drops that incidentally are given directly to the eye, so it is not through the mouth and throat intermediaries. Yes, although not always, the use of eye drops can sometimes cause the throat to feel bitter when swallowing for some people.
Apparently, this is because there are channels that connect directly between the eye glands with the nose (nasolacrimalis), and followed by the nose and throat. On closer inspection, there is a small enough hole in the inside of the lower eyelid called the lacrimal punctum (puncta).
That is why, when you are crying, taking eye drops, or doing other things that make your eyes water, the liquid will flow into the nasolacrimal ducts.
Furthermore, fluid from the eye will end up in the back channel which is directly related to the nose and throat, which is also adjacent to the esophagus. This is what will unconsciously make you feel like you can feel the tears, even the bitter taste of eye drops that you use right when you swallow.
