چکیده

The ticker characteristics of the color-receptive systems of the eye were investigatedby measuring the modulation thresholds for sinusoidal flicker of one color superimposed on abackground of a complimentary color. A procedure is outlined that allows the flickercharacteristics determined using red, green and blue stimuli to be compared. The resultsobtained indicate that the red and green mechanisms have frequency response characteristicswith about equal peak sensitivity but differing in shape at low and intermediate rates offlicker. The blue-sensitive mechanism has a reduced flicker fusion frequency which seems tobe due largely to the depressed modulation sensitivity of the mechanism. R&m;&-On ttudie les caracteristiques en papillotement des systbmes de reception de lacouleur dans l’oeil en mesurant les seuils de modulation dun papillotement sinusoidal dunecouleur superpost a un fond ce couleur compldmentaire. On expose une methode qui per-metla comparaison des caracteristiques du papillotement avec des stimuli rouge, vert et bleu.Les r6sultats indiquent que les mecanismes rouge et vert ont des caracteristiques de reponsea la frdquence qui ont a peu p&s; la mZme sensibilite maximum mais une forme differenteaux frequences de papillotement basses ou moyennes. Le mecanisme sensible au bleu possedeune frequence critique de fusion rkduite, qui semble due surtout a la sensibilitt a la modulationplus faible pour ce mecanisme. Zusammenfassung-Es wurden die Flimmerkennzeichen des Farbempfangsystems des Augesdurch eine Messung der Modulationsschwelle fur Sinusflimmerreize einer Farbe auf demHintergrund ihrer Komplementirfarbe untersucht. Es wird em Versuchsverahren beschrieben,welches es erlaubt die mit roten, grimen und blauen Reizen ermittelten Flirnmerkennzeichenzu vergleichen. Die Ergebnisse zeigen an, dass das rote und grtine System mit einer ungefahrgleichen Gipfelfrequenzemp8ndlichkeit antwortet, aber dass es bei niedrigen und mittlerenFlimrnerfrequenzen Formunterschiede gibt. Das blau-empfindtiche System ist durch eineverringerte Fusionsfrequenz, die grdsstenteils von einer verminderten ModulationsempSnd-lichkeit verursacht wird, gekennzeichnet.

Opposing effects of atropine and timolol on the color and luminance emmetropization mechanisms in chicks

This study analyzed the luminance and color emmetropization response in chicks treated with the nonselective parasympathetic antagonist atropine and the sympathetic β-receptor blocker timolol. Chicks were binocularly exposed (8h/day) for 4days to one of three illumination conditions: 2Hz sinusoidal luminance flicker, 2Hz sinusoidal blue/yellow color flicker, or steady light (mean 680lux). Atrop...

Immediate Effects of Different Screen Sizes on Visual Fatigue in Video Display Terminal Users

Background: Computer usage has rapidly grown. This is because it helps to resolve problems, i.e., encountered in daily life by individuals. Various monitor screens that have been developed affect the userchr('39')s eyes. Screen size is one of the relevant impacts. Thus, this study compared the immediate effects of two computer screen sizes on visual fatigue in Video Display Terminal (VDT) users...

Chicks use changes in luminance and chromatic contrast as indicators of the sign of defocus.

As the eye changes focus, the resulting changes in cone contrast are associated with changes in color and luminance. Color fluctuations should simulate the eye being hyperopic and make the eye grow in the myopic direction, while luminance fluctuations should simulate myopia and make the eye grow in the hyperopic direction. Chicks without lenses were exposed daily (9 a.m. to 5 p.m.) for three da...

Association of rs12913832 in the HERC2 Gene Affecting Human Iris Color Variation

Introduction: Human eye colour as a physical trait is based on the developmental biology and genetic determinants of the structure known as the iris, which is part of the uveal tract of the eye. Prediction of human visible characteristics (EVCs) by genotyping informative SNPs in DNA as biological witness opens up a new avenue in the forensic genetic. Variation of iris color rely on the amounts...
