Research shows that millions of adults are affected by dry eye each year. It’s more prevalent in women, and the chance of developing dry eye increases with age.
The simplest explanation for dry eye is the lack of tears does not keep the surface of the eye lubricated.
If you have dry eye, you will feel a scratchy sensation or feel like there is something in your eye. You also may feel a burning sensation, pain, discharge and redness. Some people may have blurred vision.
Dry eye can occur when basal (lubricating) tear production decreases, tear evaporation increases or tear composition is imbalanced. Medication, age, skin conditions, allergies, wind, smoke are among the causes.
People experiencing dry eye symptoms should consult an eye care professional to determine the cause, which guides treatment strategy.
