Title Consequences of presbyopia for visual dynamics and work with visual display units
Original title Folgen der Presbyopie für die Sehdynamik und die Arbeit am Bildschirm [in German]
Bibliographic information 1984, Vol.29, No.4-5, p.190-191. Illus. 3 ref.
Abstract Description of methods and results of examinations to determine the accommodation period of the eye, and the orientation and diameter of the pupil in 100 persons of different ages. Results are represented graphically for accommodation reaction time, accuracy of dynamic accommodation and maximum rate of accommodation as functions of age. The speed and amplitude of orientation of the eye did not depend on age, whereas a decrease in accommodative ability was seen in subjects ≥40yrs old. Subjects in this age group tend to maintain a fixed posture when working with visual display units, in order to keep their eyes at a constant distance from the screen.
