Abstract
The non-intrusive measurement of preocular tear film evaporation employs a goggle fitted on a subject and connected with apparatus for introducing air of known conditions to a goggle chamber over one eye, apparatus for controlling air movement within the goggle chamber, and apparatus for humidity measurement of the chamber air. A measure of palpebral aperture readily provides the area of the exposed eye surface, for calculating the rate of tear evaporation.
