Dry eye is a common condition that occurs when your tears do not produce adequate lubrication for your eyes, whether that means you don't produce enough tears or if you produce poor-quality tears.
If after a comprehensive eye exam your doctor concludes that further dry eye tests are need, your doctor may measure the volume of your tears as well as test their quality.
If diagnosed with dry eye, treatment may include taking medication for inflammation, using artificial tears, applying warm compresses, incorporating an eye hygiene routine, or even surgery to insert punctal plugs that keep tears from draining away and helps artificial tears last longer.
