You feel an itching sensation in your eye as if an eyelash has gotten into it. You run to the bathroom and check on the mirror only to see there’s no stray eyelash. But what you noticed is that there’s a tiny hole on your lower eyelid, which you may have failed to notice for years.

You start to wonder what the little hole is. The good news is that it’s perfectly normal – everyone has that. It’s just interesting to know what it does for your body.

The tiny hole your eyelids is called a lacrimal punctum.

The lacrimal punctum (pl. puncta) is a normal part of the human eye; some are larger compared to others. Not only may you have missed the presence of that hole but there are actually two of them, one each for the lower and upper eyelids of both eyes.

There have been misconceptions about the purpose of this lacrimal punctum, mainly that it produces tears. It does not. It is, however, part of the eye drainage system. Whereas the tear glands produce the tears, the punctum collects and drains the tears, which is why you get the sniffles after crying.

Think of the punctum as an opening of a canal, which connects your eye to the lacrimal sac. The tears then drain from the sac to the lacrimal duct located in the nose. This is the reason you’ll have a runny nose after crying.

There’s also a procedure that should stop the hole from collecting so many tears.

It involves placing tiny plugs into these holes.

Disgusting and horrible as it may sound, the medical procedure is done to stop the eye from draining so many tears, thus preventing dry eyes. Doing so actually keeps the eyes moist and healthier and more capable of fighting infections. Indications for this procedure include dry eye syndrome, keratitis, Sjogren’s syndrome and recurrent erosion of the cornea.

There are also instances in which the lacrimal punctum backfires and will reverse the flow of the fluids. That means there are cases where air, tears, discharge and even blood to come out of the tiny hole. Disgusting? Yes, but some people are actually doing that on purpose — with milk.

Aside from catching up with friends and memes, one thing I love about social media is checking out some online comics. There are a lot of good, hilarious webcomics out there that are truly worth-reading and I’m always pleased to add new ones to those I’m currently following.

Like this one by a certain fella who uses the name Portuguese Geese. In BoredPanda feature, we learn that the artist has been drawing comics since he was young. He began doing webcomics in 2015, taking inspiration from his own life. “90% of my work,” he shared, “is based off personal experience, mostly awkward ones”.

Now his stuff, which is usually about the (mis)adventures of an awkward guy, is gaining positive reactions on social media because it’s truly funny and very relatable.

For the last 300 years, the Irish people have been emigrating from their homeland, making the Irish DNA widespread. On the island of Ireland, the population is estimated to be at 6.3 million, but about 80 million people all over the world claim to have Irish blood in them.

This also means that these people mostly have Celtic blood running through their veins -- or so it has long been assumed. Now, a new study shows that the Irish DNA may be more diverse than initially thought.

New research suggests the Irish people have more varied genetic influences, including the Vikings, Anglo-Normans and the British.
