The propagation of astigmatic wavefronts through astigmatic optical systems is reconsidered in the wavefront perspective.The stepalong method for vergences, described by 2x2 matrices, is applied and augmented to produce off-axis information like the magnification.

The steady-state monocular accommodative response was measured using a new type of stimulus, a spatially bandpass filtered luminance distribution known as a difference of Gaussian or DOG. The independent variables were: spatial frequency, optical vergence, contrast, and mean luminance.

Optically induced changes in the couplings between vergence and accommodation.
The Journal of neuroscience : the official journal of the Society for Neuroscience, 1987Vergence-induced accommodation (V-A) and accommodation-induced vergence (A-V) were measured in human subjects before and after they had worn various optical devices for 30 min. Laterally displacing periscopic spectacles, which increase the required change in vergence per unit change in accommodation, caused decreases and increases in the gain of V-A ...

This study was carried out on three observers by means of a highly sensitive infra-red optometer, the principle of which is recalled, associated with other measurement techniques. We found the accommodative "resting position" to coincide with minimum astigmatic ocular aberration, but not necessarily with maximum ocular optical quality, as suggested by ...

Abstract We used a new motion stimulus displayed on a computer monitor in the ground plane to induce involuntary version-vergence nystagmus. Eye move-ments were recorded with a search coil system. The involuntary version-vergence nystagmus had both vertical version and horizontal vergence compo-nents.

A method using the generalized Coddington equations enables calculating the vergence of an astigmatic ray bundle in the vicinity of a skew ray in an optical system containing a freeform surface. Because this method requires time-consuming calculations, however, there is still room for increasing the calculation speed. In addition, this method cannot be

Monkeys wore either base-out prisms to promote changes in tonic vergence or periscopic spectacles to promote changes in the coupling between accommodation and vergence. Eye movements were recorded using the magnetic search coil technique and the monkeys were rewarded for accurate fixation.
