Abstract

An experiment is described which qualitatively measures the state of accommodative vergence under binocular viewing conditions. Results show that under conditions of forced vergence, accommodative vergence maintains a value considerably different from vergence accommodation. These results indicated that accommodative vergence and vergence accommodation are mediated by separate neural processes.
