Título Computer-specific spectacle lens design preference of presbyopic operators
Información bibliográfica Oct. 1992, Vol.34, No.10, p.1023-1027. 10 ref.
Resumen Twenty-nine presbyopic subjects who spent at least 20 hours a week at a video display terminal compared a progressive addition lens designed for this function, with another commonly prescribed task-specific lens. Each of the paired lens types was worn for four weeks and then compared directly for one week. A statistically significant (P<0.05) portion of the subjects (76%) preferred the task-specific lenses overall. It was also preferred more frequently for each feature compared, although the difference was statistically significant (P<0.05) only for utility of distance vision. Both of the task-specific designs contributed to symptomatic relief. The presence of a distance-clear zone and the absence of lens discontinuities most likely account for user preference for the task-specific lenses. That preference suggests improved performance for presbyopic computer users wearing task-specific progressive addition lenses.
