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.
