Most of us are familiar with VGA displays- the most common display format used with DOS compatible equipment. There have been other studies into the effects of different types of visual corrections upon occupational task performance. Despite the known visual compromises that occur with these types of visual corrections, these correction modalities can be successful for many patients. Although they were laboratory studies, and the tasks were performed for durations that are considerable shorter than a full work day, it is likely that similar inefficiencies occur daily for workers with uncorrected vision disorders. We might even expect that 8 hour productivity would be more greatly reduced because of the symptoms and fatigue which accompany the vision problems.
Many companies already offer vision care to their employees as a benefit of employment.
Even if a company offers vision care to all employees, it may not necessarily be meeting the needs of their VDT employees. As discussed below, proper care of the VDT employee requires more than a simple refraction, dilated examination of the inside of the eye, and provision of glasses. Also, many VDT employees require a different pair of glasses for their VDT work than that which is required for their other daily visual needs. The employee is reluctant to use their employee benefits for a pair of computer glasses, they feel that the benefits should be used to provide for their general glasses. The backbone of any care program is the capability of the doctors who are providers for that program.
