Schirmer's Test is an eye exam used to measure tear production.It involves inserting a piece of blotting paper or a strip with a colored dye on it into the lower eyelid.
The paper absorbs the tears and the amount of moisture absorbed after five minutes is measured and recorded.This measurement can help diagnose conditions such as dry eye, inflammation and allergies.
It can also help to identify the underlying cause of the dry eye.The test is non-invasive and does not cause any pain or discomfort.
