I would not use it without proper eye protection for that particular wavelength. Staring into an infrared light will probably negatively affect your eyesight. As the eyes cannot see it, your pupil will not react and you also can't judge how bright it is.

The FOV of your eyes is insane, you have usable retina more than 90 degrees off center. If you want to avoid illuminating your eyes, you need to avoid illuminating your face.
