Purpose: To compare the time between optical magnifier and portable electronic magnifier to identify the necessary information on near object.
Methods: 15 participants were asked to perform timed tasks of viewing bills and photographs to find the certain information. There were three visual impairment conditions, reduced visual acuity, cataract and constriction in visual field. Under three vision conditions, times to recognize the near object was measured.
Results: Participants were aged 21 to 26 (mean age 22.73¡¾1.28) and 9 males and 6 females. First of all, there was no significant difference between optical magnifier and portable electronic magnifier on the task of viewing near object and photograph. When comparing among the vision conditions, constriction in visual field spent significantly more time completing the task than vision conditions of reduced visual acuity and cataract.
Conclusions: Overall, optical magnifier showed similar performance compared to the portable electronic magnifier on the task of viewing near object and photograph. Constriction in visual field required more time to complete the near vision task. Therefore, it would be recommended to prescribe a certain optical aid which can expand the visual field for enhancement of reading performance.
