If the laser is powerfull enough to kill sea-lice then how does it avoid blinding the fish or giving them retina burn?

As long as the fish can still find food that might not matter in a farm environment

That seems a somewhat callous disregard for the fish, blinded and swimming around with itchy eyes from burned out retina.

Yeah, it's definitely unethical. I doubt the farmers care though
