Problem:
Question: What happens if one looks directly at infrared LEDs? Sometimes I see this kind of LED at night as red dots and I'm also courious about it.
I was wondering what would happened if one looked directly to these LEDs, because we see them everywhere like in remote controls, CCTV cameras, sensors, etc.
Question: What is the difference between infrared and visible light to our eyes? (I mean why is it impossible to look directly to visible light while we can look to infrared?)
Could someone explain this to me?
