Aroma Season What Causes Dry Eyes?

Even when you’re happy, your eyes are full of tears. They provide moisture and lubrication to help you see and keep your peepers comfortable.

What’s in a tear? They’re a mix of:
Water, for moisture
Oils, for lubrication
Mucus, for even spreading
Antibodies and special proteins that keep infection at bay
The ingredients come from special glands around your eye. Dry eyes often mean your tear system is out of whack.
When tears don’t provide enough moisture, you might notice:
A gritty feeling
Feeling like there’s something in your eye
Itching
Redness
Blurry vision
Light sensitivity
Sometimes, dry eyes create too many tears. This confusing condition is called reflex tearing. It happens because the lack of moisture irritates your eye. It sends a distress signal through your nervous system for more lubrication. Your body sends a flood of tears to try to make up for the dryness. It’s a lot like what happens when you get sand in your eye and it runs. But these tears are mostly water, so they don’t act like normal tears. They can wash debris away, but they can’t coat your eye’s surface.
What Causes Dry Eyes?
Sometimes, there's a lack of balance in your tear-flow system. Or your air conditioner, heater, or other things around you could dry out your tear film. Other causes include:
The natural aging process, especially menopause
Side effects of certain drugs like antihistamines
Diseases that affect your ability to make tears
