That's debateable. We may simply have evolved without photon sensors.

Other wavelengths may have issues with detection or the information provided; if something can cut through obstructions in the atmosphere it may be hard to grow cells which interact with it or the rays may also ignore whatever is present locally at most scales.

The eye might be reduced in detail to the same domain as hearing or smell.
