The effects of plus lenses on eye movements

1 May 1995

Abstract

This study assessed eye movements of fourteen esophoric subjects at near utilizing the OBER2 digital eye movement registration system. The OBER2 has specialized goggles that monitor eye movements as a subject views a reading passage. Subjects read one passage with their habitual distance prescription and another passage with the plus amount required to shift their esophoric posture into exophoria. Our purpose was to quantify the eye movements with the near add to determine if the increased lens power would improve the subject's visual performance and eye movement ability. Statistical analysis was done on the eye movement data under both reading conditions and no significant difference was found.
