How to Diagnose Chronic dry eye?

- Eye doctor will perform an eye exam to inspect the exterior of your eye, including the eyelids, tear ducts and how you blink
- Will examine your cornea and the interior of your eye
- Will measure the quality of your tear film

How To Treat?
The basic treatments can be divided into 4 major parts:
1.  increasing tears
2.  maintaining tears
3.  triggering tear production
4.  healing inflammation

If the condition of dry eyes are mild, it may only need artificial tears. They can be applied as needed less than four times per day.

However, if the eyes don’t change with artificial tears, it may need help keeping tears in your eyes. The tears ducts can be blocked so tears can’t drain.

Prescription eye drops or inserts can stimulate tear production. Increasing intake of omega-3 fatty acids can also help with certain causes of dry eyes.

To reduce inflammation of the eyelids or glands, may have to take an anti-inflammatory drug. Massage, warm compresses, or ointments may also help.
