Abstract:

Accommodation and binocular vergence were measured using a haploscope optometer for 10 observers who viewed collimated 0.15 diopter and noncollimated presentations of a simulated approach and landing. Collimated imagery produced a small but consistent decrease in accommodation for each observer M 12.7 meters. Collimation also produced an increase in the perceived size of objects within the visual scene. These results suggest that the primary influence of collimation is on binocular vergence and that differences in the perceived quality of collimated and noncollimated simulator displays are due to differences in binocular vergence rather than in accommodation.
