Cold Weather Goggles. 6. Effectiveness of Yellow Filters
Abstract
The visibility of bright and dark targets was compared when viewed through yellow filters whose excitation purity ranged from 0.06 to 0.98 as well as a neutral filter and whose total transmittances had been roughly equated. The visibility of large bright targets was enhanced by all the yellow filters but only to a very small degree. The visibility of the dark targets was also slightly enhanced, but these differences were not statistically significant. The color perception of both color normals and red-green dichromats was not affected by yellow filters whose excitation purity was less than 0.20.
