The use of progressive addition multifocals with video display terminals. 1986

G W Good, and K M Daum

Consideration must be given to a number of factors when designing spectacles for the presbyopic VDT worker. Video terminals are routinely positioned high within the working field, usually at an intermediate distance. It is often difficult for a practitioner to design a single pair of multifocals to satisfy the visual needs of these workers. In this investigation, different fitting designs of progressive addition multifocals were subjectively compared for 24 presbyopic VDT operators. The results were correlated with measurements taken at the workstations for each of the participants.
