Usually, an image sensor is more sensitive to near-infrared (NIR) than visible light. For normal home use operation, it is mostly preferred to have NIR spectrum part to be blocked, but for scientific, industrial or biometric applications there are a lot of cases where having unrestricted sensitivity to full spectrum is a huge benefit.
