简要总结
Video display terminal users frequently refer computer-related visual and ocular symptoms, that are the most frequently occurring health problems among such these subjects.
The Italian law has established an eye examination to assess ocular status (D.Lgs 81/08 ex law 626/96) in VDT workers: subjects are evaluated by clinical signs and symptoms. The availability of a validated questionnaire could be very useful to diagnose visual disturbances and to follow them during follow-up examinations in 2014, a Spanish group has developed and validated a questionnaire for the assessment of visual and ocular symptoms in VDT workers.
Aim of the present study is to make available to Italian health professionals a new instrument to assess asthenopic symptoms, taking into account the patient's perspective.
