| Resumen |
The purpose of this study was to test whether eyestrain during near work depends on the individual's position of convergence and/or accommodation in darkness. A VDU task which placed a predominantly static load on the ocular muscles was performed at two viewing distances. Visual strain at a viewing distance of 50cm was greater than at 100cm. The more distant the individual's dark convergence, the greater was the visual strain at the 50cm viewing distance. When subjects were free to adjust the viewing distance to their comfort level, they chose distances between 51 and 99cm (mean 74cm) with characters 5mm tall. |
