What about Infrared? Wouldn’t that be immensely useful? I’ve always wondered why no species has ever evolved infrared vision.

Thermal imaging requires specialised organs. The difference between optical and thermal wavelengths is too extreme for a single organ to cover. Long wavelength IR is also quite low resolution for visual purposes.
Snakes have evolved the capability, but it’s not common.
