Figure Legend:
Natural viewing, phoria, and stereo displays. The left panel plots phoria as a function of vergence and focal distance. The abscissa is the vergence response in diopters. The ordinate is the focal stimulus in diopters. The dashed diagonal line represents the vergence and focal distances associated with natural viewing. The purple and blue lines are examples of esophoria and exophoria, respectively. The green line represents the phoria of a typical individual: esophoric at far and exophoric at near. The right panel shows the focal distances for typical stereo devices: mobile devices, desktop displays, television, and cinema. Assuming that the vergence response is accurate, we can plot the focal distances associated with those devices on the same graph. The blue dashed lines indicate stereo content that would be farther than the screen and the purple dashed lines indicate content that would be nearer than the screen.
