[Screening and monitoring studies on employees working with video display terminals]

Ophthalmological screening of 152 employees working at VDUs was carried out. In 62% of the people tested spectacles were prescribed for correction of vision at working range. Two years later a follow-up examination was performed. The correction had to be revised for 23% of the people working et VDUs. It is recommended that ophthalmological screening should not be restricted to people working at VDUs. All employees whose work involves close-range vision require regular ophthalmological check-ups.
