Accommodation and Stereoacuity
Stereoacuity and resolution acuity were measured (1) through apertures set at various distances from S and (2) through plus lenses producing an accommodative error for the target equal to that produced by the presence of the apertures. Stereoacuity was degraded by the apertures but not by the lenses, whereas resolution acuity was degraded by the lenses but not by the apertures. Although stereoa...
متن کاملStereoacuity and colour contrast
We have measured the contrast dependence of stereoacuity using both horizontally and vertically oriented, isoluminant (red-green) and isochromatic (yellow-black), 0.5 c/deg Gabor patches. For comparison, contrasts were computed in multiples of detection threshold, where detection threshold was defined as the contrast required for the stimulus to be simultaneously detectable in each eye. Dispari...
متن کاملStereoacuity in young children.
Previous investigations of stereopsis in children have found that stereoacuity improves gradually over time and does not reach adult levels until well into childhood. The unusually protracted period of development implied by these data is at odds with the development of other visual capacities, such as acuity, contrast sensitivity, increment thresholds, and flicker fusion. When tested on those ...
متن کاملStereoacuity Following LASIK
PURPOSE To evaluate the effect of laser in situ keratomileusis (LASIK) on stereoacuity (SA). METHODS This prospective study includes 200 patients scheduled for LASIK. SA was evaluated preoperatively and one week, one month and three months postoperatively using the Random Dot test. Patients with preoperative SA worse than 480 sec/arc were excluded from the study. RESULTS The study included ...
متن کاملStereoacuity at distance and near.
PURPOSE Because previous studies have reported conflicting evidence, we examined a possible difference in stereoacuity between distance and near, in particular using a random-dot display. We compared distance and near stereoacuities using identical presentation formats at the two distances. METHODS Twelve young adults with low, stable refractive errors and apparently normal binocular vision p...
