Numerous national standards rely on subjective evaluation techniques for Plano-protective eyewear, hampered by issues like accommodation, depth of focus, the field of vision, and optical system resolving power discrepancies. For a study, researchers sought to create an objective approach for assessing the optical requirements of Plano-protective eyewear. A Wavefront Analysis Optical Tester (WFAOT) was built using a Shack-Hartmann wavefront sensor and a 542 nm collimated laser system. The WFAOT was utilized to determine the refractive power of 9 calibration lenses and the left oculars of 36 military Plano-protective eyewear. The identical samples were subjected to subjective assessment using the telescope technique defined in American National Standard Institute (ANSI) Z87.1. The association between protective eyewear refractive powers before and after a two-week delay was evaluated using a dependent t-test. For every statistical analysis, SPSS 16 for Windows was utilized. There was no difference in refractive powers of the same protective eyewear assessed before (M=-0.010, SD=0.018) and after a two-week delay (M=-0.009, SD=0.019); t(35)= -0.466, P=0.644. WFAOT is a refractive power measuring method akin to the ANSI Z87.1 telescope methodology.
