I’m confused, are you saying that the minimum amount of energy in an infrared pulse sufficient to melt a fly’s wings (< 1mm) would necessarily also damage a hum

I’m confused, are you saying that the minimum amount of energy in an infrared pulse sufficient to melt a fly’s wings (< 1mm) would necessarily also damage a human eye? I have to believe there is a threshold value of safety, particularly with IR. You can tell me I’m wrong, but please provide a bit of physics to justify it.
