The human eye is not all it’s cracked up to be. Human vision is pretty miraculous, but our eyes aren’t quite as powerful as you might imagine. What we can see is stuff that reflects or emits light with wavelengths in a very narrow band (since you ask, from about 750 to 400 nanometres). What we can’t see is the rest. That’s all matter that reflects or emits light over the other 99.99999999999% percent of the spectrum. In fact, we’re almost blind.
