Abstract
Embodiments disclosed herein include devices, systems, and methods for determining tear film break-up time and for detecting eyelid margin contact and blink rates, particularly for diagnosing, measuring, and/or analyzing dry eye conditions and symptoms. The apparatus and methods for determining tear film break-up time and for detecting eyelid margin contact and blink rates, particularly for diagnosing, measuring, and/or analyzing dry eye conditions and symptoms may employ ocular surface interferometry (OSI) devices or other imaging and display devices capable of imaging and displaying a picture of a patient's eye during tear film break-up time and blink rate related procedures.
