Functional spectacle lens evaluation chart, display method thereof, functional spectacle lens evaluation method, selection method, and manufacturing method

摘要

The functional spectacle lens evaluation chart includes first and second evaluation areas for evaluating the suitability of two types of functional spectacle lenses having different functions, and the first and second evaluation areas. Are expressed as chromaticity points (x1, y1) and (x2, y2) on the xy chromaticity coordinates, respectively, the distance ΔE = {(x1-x2) 2+ (y1-y2) on the xy chromaticity coordinates 2} 1/2 is 0.001 to 0.04, each color temperature is 4000K to 9000K, and the color temperature of the first evaluation region is lower than the color temperature of the second evaluation region. . The functional spectacle lens evaluation chart can accurately evaluate the suitability of two types of functional spectacle lenses with different functions to the wearer.
