Was wondering because I heard they were very dangerous even if not looked at directly. Wonder if looking at a picture or video can harm eyes may sound like a will question but it's always good to be on the safe side

At worst the recording device will saturate (and the camera element may be damaged), but the playback device will only generate an intensity that it is capable of. There is no danger to vision that would not normally be present with the playback device.
