IT'S A THIING (BUT
WHY IS IT SUCH A
Dry eye is a chronic disease, which means it's long-lasting and doesn't go away easily. Your eye doctor may call it "dry eye syndrome," "dry eye disease," or simply "dry eye." No matter what you call it, dry eye is a pretty common eye condition. It can also be pretty annoying, interrupting you while you read, drive, watch TV, or sneak in a little online shopping.
Not everyone experiences dry eye the same way
If you know someone else with dry eye, it may not be caused by the same factors. Symptoms may last longer or not as long. And those symptoms may be more or less severe than yours.
Signs of dry eye vs symptoms of dry eye
"Symptoms" are the things that you experience yourself, like that scratchy feeling in your eyes. "Signs" are the things your doctor can see.
WHAT'S UP WITH THOSE DRY EYES?
Ever wonder what's happening on the surface of your eyes with dry eye? And why your tears are letting things get so dry?
Scientists used to think dry eye was caused by not making enough tears. Today, we know it's more complicated than that. Dry eye is a disease of not just tear quantity, but also tear quality.
When good tears go bad
Healthy tears help lubricate, heal, and protect the surface of the eye. But when you have poor-quality tears, they can contribute to inflammation.
Inflammation and stress are in cahoots
Scientists believe that inflammation on the surface of the eye may be a key factor in causing dry eye. Inflammation is typically an immune system response to stress, irritation, bacteria, toxins, or any of a number of causes.
There are several triggers for dry eye–including prolonged screen time, dry climates, and reading a lot. They can all be sources of stress on the surface of your eyes.
That kind of stress can lead to inflammation on the surface of your eyes, which can lead to more stress. The cycle can go on and on. And your dry eye symptoms can get worse.
