Visual Discomfort and Depth-of-Field [PDF]
i-Perception, 2013 Visual discomfort has been reported for certain visual stimuli and under particular viewing conditions, such as stereoscopic viewing. In stereoscopic viewing, visual discomfort can be caused by a conflict between accommodation and convergence cues that ...

Visual Discomfort and Variations in Chromaticity in Art and Nature [PDF]
Frontiers in Neuroscience, 2021 Visual discomfort is related to the statistical regularity of visual images. The contribution of luminance contrast to visual discomfort is well understood and can be framed in terms of a theory of efficient coding of natural stimuli, and linked to ...

A mechanistic account of visual discomfort [PDF]
Frontiers in Neuroscience, 2023 Much of the neural machinery of the early visual cortex, from the extraction of local orientations to contextual modulations through lateral interactions, is thought to have developed to provide a sparse encoding of contour in natural scenes, allowing ...

Assessment of 3D Visual Discomfort Based on Dynamic Functional Connectivity Analysis with HMM in EEG [PDF]
Brain Sciences, 2022 Stereoscopic displays can induce visual discomfort despite their wide application. Electroencephalography (EEG) technology has been applied to assess 3D visual discomfort, because it can capture brain activities with high temporal resolution.

i-Perception, 2011 Natural images typically have an approximately 1/f amplitude spectrum. Images that have relatively high amplitude at low spatial frequencies in comparison with a 1/f spectrum have been found to be uncomfortable (Fernandez and Wilkins, 2008, Juricevic et ...

Pattern-Induced Visual Discomfort and Anxiety in Migraineurs: Their Relationship and the Effect of Colour [PDF]
Vision, 2021 In migraineurs, coloured lenses were found to reduce the visual stress caused by an aversive pattern known to trigger migraines by 70%, but do such patterns also produce a low-level anxiety/fear response? Is this response lessened by colour? We sought to

Visual discomfort and flicker. [PDF]
Vision Res, 2017 Flickering lights can be uncomfortable to look at and can induce seizures in observers with photosensitive epilepsy. However, the temporal characteristics contributing to these effects are not fully known. In the spatial domain, one identified source of visual discomfort is when images have Fourier amplitude spectra that deviate from the natural (∼1 ...

Development of the Japanese version of the Visual Discomfort Scale. [PDF]
PLoS ONE, 2018 BackgroundVisual stimuli, such as stripes and texts, can induce "visual discomfort" including perceptual and somatic symptoms. Individuals reporting high levels of visual discomfort might experience migraine headache and may have reduced reading ...
