The graph above shows the Maximum Permissible Exposure (MPE) to light from lasers, as joules for a given exposure time. This is most suitable for use with pulsed lasers... These charts show the eye MPEs for various wavelength ranges. They may not include the changes made in the 2014 version of the ANSI Z136.1 standard. But these should be good enough to give a broad overview... Power Density in watts per square centimeter, versus Exposure time in seconds, for selected wavelengths
