Claim One:
1. A device ( 1 ) for measuring the three-dimensional movements of an eye, said device comprising: a means for marking an array of positions on said eye whose movements are to be measured, a means for capturing the two-dimensional, digital images of said array of eye-marked positions as said eye is moved, said image capturing means having an optical axis and a prescribed spectral range, a means for illuminating said marker array with a light source whose output is in a spectral range that is chosen from the group consisting of those that are either within or outside of said spectral range of said image capturing means, a means for aligning said optical axis of said image capturing means with the center of said eye, and a means for computing the three-dimensional locations of said array of eye-marked positions from the information contained in said captured digital images.
