| Popis: | Myopes have been shown to have abnormal accommodative characteristics. This study investigated the characteristics of accommodation facility in myopic and emmetropic students. Distance and near positive and negative accommodation response time components of facility were measured over a 1 min period using a −2.00 D/zero lens pair for distance responses and a ±2.00 D lens pair for near responses. 79 students (37 myopes and 42 emmetropes) aged 18–27 years acted as subjects. Subjects were masked, and the results were analysed in a masked fashion. Mean distance facility was significantly lower (9.7 cycles per minute (cpm)) in the myopic group compared with the mean distance facility in the emmetropic group (15.6 cpm; p |
