Usually, tears are from meibomian gland dysfunction. MGD is your oil glands not getting out of your eye. The front layer of your tears is an oil layer and if the oil layer is not getting out because of obstruction due to what we have talked about previously, then your glands can become clogged. You need to be doing omega 3s, warm compresses, the lid spray, and taking care of the eyelids. If the oil layer starts to break down, what happens is your eye feels like there is something in it.
There is a different part of you eyelid called lacrimal gland that causes watery tears. If the oil layer breaks down, your eye feels like it has something in it, then your brain tells your lacrimal gland to start watering because that will wash out whatever you have in it. You and I both know you don’t have anything in it and you are just irritated. Think if you got a stick in your eye, your eye waters a lot to get it out. That is a just a reflex mechanism that we have. When the oil layer breaks down it makes you tear. Why is it one eye over the other? Could be the way you sleep, could be allergies, could be dust, it could be anything. If you are not taking a really great omega 3, that could be something to start with as well.
