Cognitive workload affects ocular accommodation and pupillary response. [PDF]
J Optom, 2023 Cognitive involvement in reading causes variations in the tonus of autonomic nerve system. The aim of this study was to examine the effect of short-term cognitive load on accommodation and pupils' absolute values and temporal variability in test persons performing three different types of tasks.We aimed to show how cognitive tasks of different type and

Seeing the future: Predictive control in neural models of ocular accommodation. [PDF]
J Vis, 2022 Ocular accommodation is the process of adjusting the eye’s crystalline lens so as to bring the retinal image into sharp focus. The major stimulus to accommodation is therefore retinal defocus, and in essence, the job of accommodative control is to send a

Is Ocular Accommodation Influenced by Dynamic Ambient Illumination and Pupil Size? [PDF]
Int J Environ Res Public Health, 2022 Purpose: We investigated ocular accommodative responses and pupil diameters under different light intensities in order to explore whether changes in light intensity aid effective accommodation function training.

Ocular accommodation and wavelength: The effect of longitudinal chromatic aberration on the stimulus-response curve. [PDF]
J VisThe longitudinal chromatic aberration (LCA) of the eye creates a chromatic blur on the retina that is an important cue for accommodation. Although this mechanism can work optimally in broadband illuminants such as daylight, it is not clear how the system

Determining the relative contribution of retinal disparity and blur cues to ocular accommodation in Down syndrome. [PDF]
Sci Rep, 2017 Individuals with Down syndrome (DS) often exhibit hypoaccommodation alongside accurate vergence. This study investigates the sensitivity of the two systems to retinal disparity and blur cues, establishing the relationship between the two in terms of ...

The quest for the human ocular accommodation mechanism. [PDF]
Acta Ophthalmol, 2020 We have known the accommodation phenomenon since 400 BC. Hypotheses about its mechanisms varied widely for two millennia. Early in the 17th century, when people became more aware of ophthalmic optics, Scheiner and Descartes were close to solving that ...

On voluntary ocular accommodation [PDF]
Perception & Psychophysics, 1975 Young observers were challenged to induce a marked monocular accommodative response to a relatively weak accommodative stimulus by placing a-9 diopter contact lens on the eye. At first, observers could not produce the desired response, but with training, three of four subjects achieved criterion.
