Will it hurt the camera to hold the digital camera lens with infrared light that we usually play? Seek an answer

No, infrared rays have no effect on the lens at all. An infrared filter is installed in front of the sensor (CCD, CMOS) of the camera, which can filter infrared rays without affecting imaging. Some machines with infrared photography function (Sony F717,828, etc. ) In fact, you can remove this filter. Because it is an infrared filter, most of the infrared rays are ignored before entering the sensor, so it will not harm the camera. But the camera should not face too strong light sources such as sunlight for a long time.
