Osmolarity is the accepted standard for diagnosing Dry Eye Disease. The TearLab Osmolarity Test will give your doctor a meaningful measurement of the health and stability of your tear film. Once your eye doctor has determined your osmolarity number using TearLab, he or she can design a treatment regimen tailored to your specific condition.
