METHOD FOR PRESENTATION OF NEW OPTOTYPES, WHICH DISCRIMINATION REQUIRE GLOBAL INFORMATION INTEGRATION BY THE HUMAN VISUAL SYSTEM, TEST SYSTEM FOR MEASURING REFRACTIVE ERROR AND CONTRAST SENSITIVITY, AND COMPUTER PROGRAM PRODUCT

摘要

A method for displaying optotype representations to assess at least one of a refractive error or a contrast sensitivity of the visual system of a test person comprises providing (11) a plurality of optotypes, comprising a base pattern and one or more modulated versions of said base pattern, wherein a contour of said base pattern is defined by a closed curve and said one or more modulated versions of said base pattern have contours being defined by modulated versions of said closed curve; providing (12) a test system (30) for measuring at least one of a refractive error or a contrast sensitivity of the visual system of a test person; and displaying (13) representations of said plurality of optotypes via a display device (31) of said test system (30).;Further, an optotype representation and its use in a test of visual system, a test system and a computer program product are provided.
