Effect of short wavelength absorbing filters on Farnsworth-Munsell 100 Hue test and hue identification task performance.
The influence of four short wavelength absorbing filters (yellow filters) on performance of the Farnsworth-Munsell 100-Hue test and three hue identification tasks was assessed in 10 color-normal observers. The yellow filters included the NoIR 40% Amber, Vuarnet No. 4006, Corning CPF 550, and Blu Blocker. A neutral density filter and a no-filter condition served as comparisons. Results showed that the Vaurnet, CPF 550, and Blu Blockers significantly lowered performance on the Farnsworth-Munsell 100-Hue test and the color-dependent tasks below levels obtained in either the neutral-density filter or no-filter conditions.
