Dry eye is a multifactorial disease of the tears and ocular surface that results in symptoms of discomfort, visual disturbance, and tear film instability with potential damage to the ocular surface. It is accompanied by increased osmolarity of the tear film and inflammation of the ocular surface. 1

Put a check mark next to the symptoms you have experienced.
In fact, dry eye disease occurs when your eyes do not produce enough tears or produce poor quality tears. That’s why it’s essential you get your tears analyzed by your eye doctor. Only an eye doctor can properly diagnose your problem and treat it appropriately.
Your eye doctor will take a sample of tears from each eye and use the TearLab device to measure osmolarity (the saltiness of your tears). As osmolarity in your tears increase ocular surface cells become damaged. Your doctor will need an amount of tear fluid no larger than the period at the end of this sentence.
