infrared rays
Some night vision goggles detect the infrared signatures of people and objects. Heat travels from a fireplace as infrared radiation.
Pulsars are best observed in the radio part of the electromagnetic spectrum. This is because their strong radio emission allows them to be detected and studied using radio telescopes. However, pulsars have also been observed at other frequencies, including X-ray and gamma-ray wavelengths.
Isaac Newton created the first color wheel in 1666 when he discovered a visible color spectrum using a prism.
Tornadoes are detected using Doppler weather radar. In recent years some of these radars have been upgraded with dual-polarization to further aid in detectng hail and tornadic debris.
Because many stars emit energy unevenly over the electromagnetic spectrum. Thus extremely energetic objects would be brighter in X-rays (more energetic than visual light) and some brown dwarfs would be easier to perceive in the infrared. Combining images from across the spectrum avoids the three blind men and the elephant issue.

It works great at night. Even one that does not have nightvision works pretty well using your backup lights.

Using lab goggles is pretty easy. Put them on your head. Adjust them to fit properly and wear them. http://www.gogglesandglasses.com
1300 or earlier: Persian divers were using diving goggles with windows made of the polished outer layer of tortoiseshell. 1730. In France, Guy Gilpatrick started swim diving with waterproof goggles, derived from swimming goggles (which were originally intended to keep salt water out of the eyes at the surface).
