Experimental data obtained with these methods, along with a more exact knowledge of the anatomy (asphericities) of the optical surfaces of the eye, permit us to build more accurate models of the optical system of the eye, learn about its wide-angle optical design, and develop applications....
The human eye is affected by large chromatic aberration. This may limit vision and makes it difficult to see fine retinal details in ophthalmoscopy. We designed and built a two-triplet system for correcting the average longitudinal chromatic aberration of the eye while keeping a reasonably wide fie...
Off-axis aberrations of a wide-angle schematic eye model This model captures the main features of the wide-angle optical design of the human eye with minimum complexity: four conic optical surfaces plus a ... I Escuderosanz,R Navarro - 《Journal of the Optical Society of America A Optics ...
Two cylindrical lenses of equal power, one positive and one negative, were used to correct astigmatism of oblique incidence in a wide-angle optical model of the human eye. Tangential and sagittal vergences were calculated at different visual angles from the posterior pole to the peripheral retina...
The Human Eye an Optical Filter The properties of the image-forming elements of the human eye are compared with the properties of the retina-brain system by considering them as two linear... FW Campbell - 《Proceedings of the IEEE》 被引量: 116发表: 1968年 The wide-angle point spread fun...
In the Eye_Binocular.zmx model (below), the interpupillary distance (PD) and convergence angle of this model can be set using the parameters of the null object “Reference Point 1”. Axial source rays have been added to represent the lines of sight projected to an object surface. (In re...
Open Angle Glaucoma, an optic neuropathy characterized by loss of RGCs, is one of the most common causes of vision loss world-wide and the leading cause of irreversible blindness among African Americans51,52. Among genes implicated in glaucoma, either by GWAS or as rare Mendelian alleles, most...
On the other hand, when I get a good wide angle or scenic shot I hardly even bother to post a web-sized graphic or make a small print (and I’m not going to start for this article). I want it printed BIG. I think perhaps so that my human vision can scan through the image pick...
The visual axis is a nodal ray19 of the eye that intersects the fovea. The angle α is the angle between the visual axis of the eye and the optical axis12. The visual axis is generally displaced nasally and superiorly within the visual field relative to the optical axis. The horizontal ...
(covert) eye dominance from objective (overt) eye movements, thereby avoiding the confounds and biases of volitional reports46. Briefly, participants dichoptically viewed two horizontally moving gratings through a mirror stereoscope, while we recorded optokinetic nystagmus (OKN) in one eye. The slow...
