Visual Psychophysics and Physiological Optics Experimental Simulation of Simultaneous Vision
METHODS. The instrument provides the eye with two superimposed images, aligned and with the same magnification, but with different defocus states. Subjects looking through the instrument are able to experience pure simultaneous vision, with adjustable refractive correction and addition power. The instrument is used to investigate the impact of the amount of addition of an ideal bifocal simultan...
متن کاملVisual Psychophysics and Physiological Optics Visual Acuity, Crowding, and Stereo-Vision Are Linked in Children with and without Amblyopia
METHODS. We measured the covariation between these four abilities in children 4 to 9 years of age (n1⁄472) with strabismus, anisometropia, or mixed strabismus/anisometropia, and unaffected controls. Children reported the orientation of a target (a modified ‘‘Pac-Man,’’ similar to Landolt-C stimuli) using four ‘‘ghosts’’ as references. Using a modified staircase procedure we measured threshold s...
متن کاملEcological optics and visual slant.
Flock's "A Possible Optical Basis for Monocular Slant Perception" is criticized as being a theory of stimuli rather than a theory of perception. To account for accurate monocular slant perception, the theory requires 9 assumptions, including the unproved ability of the eye to register random texture density. The alternative hypothesis is proposed that monocular visual slant is a function primar...
متن کاملVisual Psychophysics and Physiological Optics Wavelength Dependence of the Ocular Straylight
Citation: Ginis HS, Perez GM, Bueno JM, Pennos A, Artal P. Wavelength dependence of the ocular straylight. Invest Ophthalmol Vis Sci. 2013;54:3702–3708. DOI:10.1167/ iovs.13-11697 PURPOSE. Ocular straylight is the combined effect of light scattering in the optical media and the diffuse reflectance from the various fundus layers. The aim of this work was to employ an optical technique to measure...
متن کاملVisual Psychophysics and Physiological Optics Perceptual Learning Improves Stereoacuity in Amblyopia
Citation: Xi J, Jia W-L, Feng L-X, Lu Z-L, Huang C-B. Perceptual learning improves stereoacuity in amblyopia. Invest Ophthalmol Vis Sci. 2014;55:2384–2391. DOI:10.1167/ iovs.13-12627 PURPOSE. Amblyopia is a developmental disorder that results in both monocular and binocular deficits. Although traditional treatment in clinical practice (i.e., refractive correction, or occlusion by patching and p...
