I don't know about the health risks and harms, but it sure as hell is annoying if nothing else. I don't think it's due to PWM specifically, but the light in my fridge strobes at the mains frequency, so it "samples" my arm as I move it around in there when picking stuff out. But 50 Hz is extremely low - so it looks like as if my arm's movement "stuttered". Super jarring.
Not sensitive to this thankfully, so apart from making me act a diva and pissing me off, it doesn't affect me, but I sure wish I understood the EE side of it all so that I could properly avoid all these lights, at least in my own home.
