| Resumen |
In an experimental design with two matched groups (n=13 and n=17) working for 2h and 4h respectively, followed by a 15min restitution time, the study examined the effect of continuous VDT work on: (1) visual acuity, refraction and oculomotor functions (ZCSV: zone of clear, single vision) and (2) the effect of 15min restitution time on the oculomotor functions (ZCSV). In both groups there was a significant reduction in visual acuity, refraction changes in myopic direction and reduced ciliar and vergence muscle capacity. The ZCSV changes were temporary and a 15min restitution period restored approximately half of the ZCSV changes. There were no significant differences between 2h or 4h of VDT work on any of the variables examined. |
