The damage at those wavelengths is just overheating. Your eyes are mainly water with its absurdly high heat capacity compared to pretty much anything in an image sensor. I'd expect eyes to be much more resilient in short duration, high intensity exposures and significantly better at long duration, low intensity exposures. LIDARs have been shifting towards short duration exposures to get higher intensities (for range) in recent years, simply to stay under the class 1 limits.

The short exposure is putting a lot of faith in these device manufacturers. How do they guarantee short duration, are you confident that each manufacturer has sufficient electronics to stop the laser if the spinning slows slightly due to dirt, low power or a crash? Should the exposure limits be the same during day vs. night when your pupils are dilated?
