Abstract
We analyzed the effect of modified mono-vision prescription on the occupational progressive addition lenses (OPALs) in presbyopia for indoor use as a method to solve the inconvenience caused by the decrease in the intermediate and the near distances' vision when the PALs worn. To analyze the effect, 37 subjects (57.22â±â5.18 years) were selected who were wearing PALs and had working hours over 6âh per day on average at intermediate and near distances. Entire tests were carried out with regard to three cases: subjects wearing PALs, occupational progressive addition lenses (OPALs), and prescription for modified mono-vision of OPALs. In order to compare visual performance of three cases, our study evaluated corrected visual acuity and subjective satisfaction at far, intermediate and near distances, stereo-acuity and phoria at far and near distances. The results showed that the prescription of modified mono-vision of OPALs could be useful when applied to the clinical practices for prescribing presbyopic correction.
