LipiView II, by Tear Science, (now called TearScience™ LipiView™ II Ocular Surface Interferometer) is a device that measures lipid layer thickness, evaluates blink rate, and visualizes meibomian gland structure to determine lipid deficiency, and detect MGD in its earliest stages. It aids in the evaluation of lipids and lid closure during blinking.
