To simulate medium level "dry eye" and investigate the effect of "blink" rates in "dry eye" condition using a novel porcine dry eye model (pDEM). ⋯ Different severity levels of "dry eye" can be simulated using the newly developed pDEM. Increased blink rate may protect the cornea against desiccation-induced damage; however, increased blink rate may also increase shear force between the cornea and conjunctiva and result in mechanical damage because of increased frictional force.
