You're assuming that all frequencies of microwave radiation are dangerous. Tesla lived to a 86 years, despite his exposure to it. Cell phone towers use microwave frequencies.

Television Goggles

In 1963, avid inventor and tech enthusiast Hugo Gernsback was photographed by Life Magazine showing off his "teleyeglasses" - a precursor to modern head-mounted displays.

Apparently, the idea of television eyeglasses came to the inventor in 1936, but it wasn't until the 1960s that advancements in tech made his vision possible. The television goggles used small cathode-ray tubes for the display and included a separate screen for each eye, much like modern VR headsets. The large antenna made this device look alien-like and it was certainly well before its time.
