  • Abstract
  • Look Inside

The state of accommodation during fatigue induced by ocular or physical strain has been evaluated with use of photolectric accommodo-gram (PEAG). The TEAG incor porates an infrared optometer and the time of accommoda-tion is recorded by means of polyrecorder. The studies have been made on two intelligent, co-operative test subjects.

A prolonged relaxation time over contraction time was noted during ocular strain induced by flickering stimulation, watching television or reading. Both values were prolonged following physical strain.
