What Causes Dry Eyes?

Dry Air

Dry air is one of the most common causes of temporary dry eyes. If individuals have decreased tear production due to age, they might notice dry air affects them more than it used to. Dryness in the air doesn't stop the body from producing tears, though it does cause tears to evaporate at an increased pace. Wind and moving air from an air conditioner or fan can lead to increased evaporation. If an individual's tears evaporate at a faster rate, they aren't able to lubricate their eyes or protect them from irritants. 

One way individuals might be able to treat the condition indoors is by adding a humidifier to their home. Humidifiers spray moisture into the air, helping reduce dryness. Pollutants like smoke can make eyes sting and dry out, so individuals should be cautious if they're camping or if they live in an area near wildfires. Individuals in desert climates may be more susceptible to dry eye, especially during the hot summer months.
