There’s nothing more uncomfortable than a set of dry eyes! This occurs when there isn’t enough lubrication in the eyes from tears. While it can happen in one eye at a time, it usually affects both eyes at the same time and can happen for many reasons, such as staring at a computer screen, riding a bike, or even allergies. It will likely cause your eyes to sting and burn.

You might think tears are only for crying, but they actually serve a bigger purpose. They are meant to keep our eyes moist and well lubricated. They’re made from a mix of water, oils, mucus, and antibodies that keep infection at bay. When a person is experiencing dry eyes, it generally means their tear system isn’t working as it should.
Here’s a look at some of the common causes behind chronic dry eyes…
1. You Have an Autoimmune Disorder
Studies show that chronic dry eye can be a symptom of several autoimmune disorders—such as scleroderma, lupus, Sjögren’s Syndrome, Grave’s disease, and rheumatoid arthritis.
For example, research from Michigan University’s Kellog Eye Center, report that Grave’s disease is a type of thyroid disorder that can impact the muscles and tissues around the eye, including the tear ducts, resulting in decreased tear production.
