In addition to blocking laser threats, laser eye protection (LEP) can cause color confusions for pilots. We developed and validated a novel method of measuring LEP effects on the discrimination, detection, and localization of chromaticity differences corresponding to yellow and white in the central and peripheral visual fields. Signal Detection Theory measures of sensitivity and response bias were calculated. The central LEP condition resulted in significantly worse performance than a No LEP condition, but with enough contrast discrimination with LEP was achieved. The peripheral task showed a same color bias and discrimination was close to chance even at maximum contrast.
