Accommodative Tracking: A Trial-and-Error Function

  • Chapter
Neurological Control Systems

Abstract

Fincham [19] and Campbell and Westheimer [12] have reported that the accommodative tracking system utilized a variety of subtle clues for focus errors of less than 1 diopter. Specifically, Fincham emphasized the role of the color fringes due to the eye’s chromatic aberration, and the use of changes in fixation in determining the initial direction of an accommodative effort. Later Campbell and Westheimer confirmed Fincham’s findings with respect to chromatic aberration and reported that the eye’s spherical aberration and astigmatism could also act as stimuli for accommodative tracking in some subjects. Fincham was unable to demonstrate the usefulness of spherical aberration as a clue.
