Vision screening and symptoms among VDT users
We conducted eye examinations on 79 subjects who used visual display terminals (VDTs) for a significant portion of their normal working day. The examination included the detection of ocular pathology, near and intermediate visual acuity, accommodative facility, fusional vergences, near point of convergence, fixation disparity, near horizontal heterophoria and colour vision. Each subject maintained a diary over five working days in which they recorded the frequency and intensity of symptoms experienced. Symptoms were classed as either ocular (discomfort) or visual (blur) symptoms. Multiple regression analysis techniques were used to investigate the relationship between symptoms and eye examination results and demographic characteristics of subject gender, age and experience with VDTs. None of the eye examination findings were significantly associated with symptoms and of the demographic variables, only VDT experience was significantly associated with symptom rates. Statistical associations were limited in a number of measures by the relatively small population of VDT users sampled.
