If visible light has more energy than microwaves, why isn't visible light dangerous?
Light waves are a type of electromagnetic wave and they fall between 600-700 nm long. Microwaves are less energetic but seem to be more dangerous than visible light. Is visible light dangerous at all and why not?

@ZeroTheHero : depends on the intensity of microwave radiation. If it can cook our meals, it can cook us :-(. For example, it can cause blindness and sterility through thermal effect. See osha.gov/SLTC/radiofrequencyradiation/hazards.html

If you stare at the Sun you’ll go blind. And if you spend a lot of time in the sun, you’re likely to get skin cancers. So visible light seems plenty dangerous to me.
Some of the damage may actually be from infrared and ultraviolet light, but these are close in frequency to visible light and very far from microwaves.
By the way, the intensity also matters, not just the frequency. In terms of photons, it matters not only how energetic each photon is, but also how many photons are arriving per second.
