title: Analysis of blink-induced vertical motion of contact lenses.
abstract: This report discusses blink-induced vertical motion of contact lenses as measured with a slit lamp. The motion seen this way represents the displacement of the lens from its position just before a blink to its position immediately after the blink. Motion amplitudes reported in the literature will be discussed in the context of a hypothesis which seeks to account for lens motion by taking into consideration the post-lens tear film characteristics, the diameter of the lens, and the geometry of the anterior segment of the eye.
