The human eye maintains a stable level of moisture and eliminates foreign particles by producing tears. When your eyes are too dry or too wet, you may be given Schirmer’s test. Dry eyes feel uncomfortable. If you have dry eyes, your eyes may sting or burn. Before the test is administered, your optometrist will put numbing drops into your eyes. He or she will pull out your bottom eyelid and gently place a special strip of paper underneath the lid. Both eyes may be tested at the same time. You will gently close your eyes and keep them shut for about five minutes with the paper strip in place. The doctor will then measure the amount of moisture on each paper strip.
