Comparison Methods for Measuring Interpupillary Distance

Overview

About this study

This research study is about measuring the distance between the sighting directions of the two eyes.  This distance is critical for the proper fitting of lenses in glasses.  The most commonly used method currently uses an instrument that measures the distance between two reflections off the corneas that are usually not at the pupil centers.  We propose that the sighting direction of the eyes is more likely to pass through the centers of the pupils than along a direction through the corneal reflections.
