Structure of the tear film during the blinking process.
The structure of the tear film was photographed immediately prior and subsequent to lid closure with a magnification factor of 140 X. Deformations of the tear film were observed in the form of "creasing", "wave motion" and also "fairly rough graininess" which point to a remarkably stable consistency of the lipid layer.
