Effect of laser eye protection devices on color perception

J Opt Soc Am A Opt Image Sci Vis. 2023 Mar 1;40(3):A9-A15. doi: 10.1364/JOSAA.477131.

Abstract

Laser eye protection (LEP) devices may alter how colors are perceived in visual displays. This study investigates changes in color perception experienced by color-normal observers while wearing LEPs. Color perception with and without LEPs was measured using clinical color tests: City University Color Assessment and Diagnosis, Konan Medical ColorDx CCT-HD, and Farnsworth-Munsell 100-Hue. All LEPs induced a shift in color perception. The level of change in color perception significantly varied across LEPs. Consideration should be made when designing color displays where LEP devices are worn.
