Abstract

Lately a method to record the aerial retinal image of a point test after double pass through the optical media of the eye was developed at the Instituto de Optica (Santamaría et al. 1987). Until now we used a point source as fixation target so that it served as the stimulus for accommodation. Here we explore how the visual stimulus affects the shape of the point spread function (PSF), or equivalently the modulation transfer function (MTF). For that purpose, we compare gratings with point sources to determine how they can affect or modify the refractive state of the eye, and in consequence, the shape of the PSF and MTF.
