The human eye doesn't perceive the infrared light. It carries too little energy and cannot cause a photochemical reaction in the visual pigments. The HQRP flashlight has the 620-630 nm wavelength that approaches as closely as possible the boundary of the infrared emission so that it became the least irritating to the eyesight of human or animal.
