An all new optical showroom experience is just around the corner. You'll have to see it to believe it.
Did you know that watering eyes can be a symptom for dry eye disease? Let us fill you in on the details! This form of dry eye disease is caused by poor quality of tears. Our tear film is composed of three different layers that must work together to be effective in keeping our eyes lubricated. The very bottom layer of the tears closest to the cornea (the clear dome-like structure of our eye), is called the mucin layer. This layer is responsible for keeping your tears attached to your cornea. The next layer is called the aqueous layer, or water layer, this layer is produced by your lacrimal gland. If you don't have enough of this layer, you probably have Dry Eye Syndrome, but that's a topic for another day! The layer we are going to be talking about today is the lipid, or oil, layer of your tears. This layer is responsible for keeping you aqueous layer on your eyes. If you don't have enough of this layer, guess what... Your tears fall off your eyes! This is why you can have dry eye symptoms even if your eyes water. This layer of your tears is made by glands that line your upper and lower eyelids. If these glands are not working properly, symptoms include, of course, watering, but it can also seem like you are looking through a film. The medical term given to this condition is Meibomian Gland Dysfunction. The good news is that there are treatment options! Do these symptoms sound familiar?
