Most of the solar radiation that reaches the Earth is visible and infrared light
Here's the spectrum of solar radiation:

Visible light has the highest irradiance or intensity. The human eye seems to be well adapted to make use of that wavelength band of solar radiation of which there is the most.
Notice that the yellow area represents solar irradiation without absorption by the atmosphere. The red area represents solar irradiation with absorption by the atmosphere taken into account. Water vapor is a pretty significant absorber in the infrared band. Oxygen (O2) absorbs a very narrow band in the near-visible part of the infrared part. Carbon dioxide absorbs some near in the area near 2000 nm.
