  • Publication number: 20210093182
    Abstract: The invention relates to a method for characterizing a visual system of a subject using measures of the sensitivity to contrast, the visual system comprising visual signal processing elements each having an impact on the sensitivity to contrast, wherein a visual test where visual patterns having different spatiotemporal frequencies and with varying luminance levels and with varying levels of visual degradation of the visual patterns are shown to a subject to measure the sensitivity to contrast of said subject, is performed, wherein a predetermined response model of a visual system is preestablished on the basis of a determination of the visual signal processing element that predominantly limits the sensitivity to contrast for each value of luminance and spatiotemporal frequency, said predetermined response model relating the visual signal processing elements predominantly limiting the sensitivity to contrast to the luminances and to the spatiotemporal frequencies, wherein at least one of the visual signal pro

  • Publication number: 20200383563
    Abstract: The invention relates to a method for selecting a color filter intended to be worn by a subject in order to improve his visual performance for a given visual task to be realized in a given environment. According to the invention, said method comprises the steps of: —submitting said subject to a colored spatio-temporal visual stimulus adapted to evaluate said visual performance for said given visual task, said stimulus being designed so that its chromaticity may be modified; —evaluating the visual performance of the subject based on his visual perception of said visual stimulus, the chromaticity of the visual stimulus taking at least two distinct values, each chromaticity being uniform; and —selecting said color filter based on the results of said evaluation. The invention further proposes an optical article comprising such a color filter. The invention finally provides a system for selecting a color filter using said method.
