Aids for color vision deficiency: introduction to the feature issue.

Publication Type: Academic Journal

Source(s): Optics express [Opt Express] 2022 Dec 19; Vol. 30 (26), pp. 46560-46563.

Abstract: Approximately 8% of Caucasian males and 0.5% of females have congenital red-green color vision deficiencies (CVD), and a number of eye diseases are accompanied by acquired CVD. This feature issue includes ten contributions regarding existing and propos...

Color Vision Testing, Standards, and Visual Performance of the U.S. Military.

Publication Type: Academic Journal

Source(s): Military medicine [Mil Med] 2023 Jan 04; Vol. 188 (1-2), pp. 49-57.

Abstract: Introduction: Color vision deficiency (CVD) is a disqualifying condition for military special duty occupations. Color vision testing and standards vary slightly among the U.S. military branches. Paper-based pseudoisochromatic plates (PIPs) remain a scr...

Nonlinear cortical encoding of color predicts enhanced McCollough effects in anomalous trichromats.

Publication Type: Academic Journal

Source(s): Vision research [Vision Res] 2023 Feb; Vol. 203, pp. 108153. Date of Electronic Publication: 2022 Dec 02.

Abstract: Nonlinear encoding of chromatic contrast by the early visual cortex predicts that anomalous trichromats will show a larger McCollough effect than normal trichromats. In Experiment 1 we employed the McCollough effect to probe the cortical representation...

Sunlight exposure cannot explain "grue" languages.

Publication Type: Editorial & Opinion

Source(s): Scientific reports [Sci Rep] 2023 Feb 01; Vol. 13 (1), pp. 1836. Date of Electronic Publication: 2023 Feb 01.

Fundamentally different representations of color and motion revealed by individual differences in perceptual scaling.

Publication Type: Academic Journal

Source(s): Proceedings of the National Academy of Sciences of the United States of America [Proc Natl Acad Sci U S A] 2023 Jan 24; Vol. 120 (4), pp. e2202262120. Date of Electronic Publication: 2023 Jan 20.

Abstract: The coordinate frames for color and motion are often defined by three dimensions (e.g., responses from the three types of human cone photoreceptors for color and the three dimensions of space for motion). Does this common dimensionality lead to similar...

The effect of a short-wave filtering contact lens on color appearance.

Publication Type: Academic Journal

Source(s): Journal of vision [J Vis] 2023 Jan 03; Vol. 23 (1), pp. 2.

Abstract: We assessed the effect of a contact lens that filters short-wavelength (SW) visible light on color appearance. These effects were modeled and measured by direct comparison to a clear contact lens. Sixty-one subjects were enrolled, and 58 completed as c...

CVD-MET: an image difference metric designed for analysis of color vision deficiency aids.

Publication Type: Academic Journal

Source(s): Optics express [Opt Express] 2022 Sep 12; Vol. 30 (19), pp. 34665-34683.

Abstract: Color vision deficiency (CVD) has gained in relevance in the last decade, with a surge of proposals for aid systems that aim to improve the color discrimination capabilities of CVD subjects. This paper focuses on the proposal of a new metric called CVD...

Understanding insect colour constancy.

Publication Type: Academic Journal

Source(s): Philosophical transactions of the Royal Society of London. Series B, Biological sciences [Philos Trans R Soc Lond B Biol Sci] 2022 Oct 24; Vol. 377 (1862), pp. 20210286. Date of Electronic Publication: 2022 Sep 05.

Authors:

Abstract: Colour constancy is the ability to recognize the colour of objects despite spectral changes in the natural illumination. As such, this phenomenon is important for most organisms with good colour vision, and it has been intensively studied in humans and...

Exploiting colour space geometry for visual stimulus design across animals.

Publication Type: Academic Journal

Source(s): Philosophical transactions of the Royal Society of London. Series B, Biological sciences [Philos Trans R Soc Lond B Biol Sci] 2022 Oct 24; Vol. 377 (1862), pp. 20210280. Date of Electronic Publication: 2022 Sep 05.

Abstract: Colour vision represents a vital aspect of perception that ultimately enables a wide variety of species to thrive in the natural world. However, unified methods for constructing chromatic visual stimuli in a laboratory setting are lacking. Here, we pre...

Reduced ability to discriminate colours - an under-recognised feature of depressive disorders? A pilot study.

Publication Type: Academic Journal

Source(s): International journal of psychiatry in clinical practice [Int J Psychiatry Clin Pract] 2022 Sep; Vol. 26 (3), pp. 321-326. Date of Electronic Publication: 2021 Oct 24.

Abstract: Background: Although in clinical practice an impairment of sensory perception is frequently reported by depressed patients no mention of these symptoms is made in DSM-5, ICD-10 or ICD-11. Previous studies on colour perception have largely relied on pat...
