Can certain laser demonstration videos affect your vision?

Hi guys,

I just watched this demo video entitled "1W 445nm Blue Laser Burning Tests" and started feeling an odd pain in my left eye. It could be entirely psychological, but I was wondering: is it possible for video demonstrations to adversely affect ones vision?

Here's the video: YouTube - 1W 445nm Blue Laser Burning Tests

Thanks!

No, a video of a laser is not the same AT ALL as looking at the actual laser :p
Your "pain" is either completely psychological or you are just sensitive to bright light itself.

No as Human said, it's the physical burning power of the laser that causes blindness to your eyes, not the colour. (Although the colour can have some effect)

Monitors couldn't put out enough power to harm your eyes.

Watching a video can have a temporary effect on color vision, but not cause damage. People that remember using the old green-on-black monitors will probably have noticed that the room around them appeared pinkish after staring at such a screen for a long time.

Besides that a video of anything (laser or otherwise) can never do any more damage to your eye than a fully white screen could... in which case you'd burn out your eyes editing a word document etc ;)

Now that is strange and true!

In the same way that you can get malaria when watching an Animal Planet special about the Congo.
