Nearpoint lens therapy and the relief of asthenopic symptoms in VDT operators

1 May 1982

Abstract

The widespread use of VDT's and information processing systems in office settings has led to numerous complaints of eyestrain and headaches among their operators. These symptoms suggest to the eye care practitioner that the visual system is under stress. It was hypothesized that a nearpoint lens therapy would relieve these symptoms. A particular method of binocular refraction and case analysis developed by C. Michael Smith, O.D., was used to determine a nearpoint spectacle prescription. Four case studies are presented of VDT operators whose symptoms of eyestrain and headache were relieved through the use of this nearpoint lens therapy.
