Exactly, it's the same with unshielded microwaves, and it's astonishing that someone would think it's safe to crank the power on these lasers with that justific

Exactly, it's the same with unshielded microwaves, and it's astonishing that someone would think it's safe to crank the power on these lasers with that justification. > When injury from exposure to microwaves occurs, it usually results from dielectric heating induced in the body. Exposure to microwave radiation can produce cataracts by this mechanism,[28] because the microwave heating denatures proteins in the crystalline lens of the eye (in the same way that heat turns egg whites white and opaque). The lens and cornea of the eye are especially vulnerable because they contain no blood vessels that can carry away heat. https://en.wikipedia.org/wiki/Microwave#Effects_on_health https://en.wikipedia.org/wiki/Microwave#Effects_on_health
