Stimulus field subtense was 3.5, and a mean luminance was 10 cd/m2. Laser exposures (doubled Nd:glass, 530-nm wavelength, 20-ns pulsewidth) were presented in Maxwellian-view and formed a 12.5 diameter spot centered on the fovea. The independent variables were: (1) test grating contrast (10%, 98%); (2) test grating spatial frequency (1, 4, 12 c/deg); and (3) laser exposure average energy (1% to 94% retinal maximum permissible exposure). The dependent variable was flashblindness, operationally defined as the time between a laser exposure and the first response in a pair of consecutive correct responses (referred to as time to criterion ).
