Hello, I want to share this here both as a question and as an alarm to anyone reading this who uses or will use lasers. When I went on to buy my first blue 1W 445 nm laser, it was off an internet post. The guy selling it proceeded to show it to me, us both unprotected, in a bright sunlight...

I am not sure yet what is the answer. It seems it’s either a) No, 380-500 nm lasers are not used for light shows; b) They are but shouldn’t or c) It’s a myth; the light is not THAT dangerous.

Yes, this is what I thought... also if generally blue light is bad, I suppose it should not be projected in people’s eyes...

I figured out I am wondering. How is it possible for blue lasers to be used in laser shows (even when diffused, thus much less powerful), if the blue light in any strength is considered to possibly cause photochemical damage to the eye?

Hello, I randomly saw this happening at a fair in Bulgaria. The laser is scanning right in the eyes of the buyers from thus stand as well as kids are playing among the figures. Is this a safe situation?

I have no other good place to post this question, so please bear with me. I was recklessly shown how a 1W 445 nm laser burns paper, lights a match and melts a plastic cap. The demonstration happened outside. I did not know all that I know now about lasers at the time of the event. I looked...

You will not easily get flash blindness off from a 455 nm laser, even less so from 405, so don’t rely on flash blindness to be your red flag. I observed the dot of a 455 from 1 meter on soil and while burning paper for about 30 seconds total and watched the beam in dark sky twice. My vision...

Steve, it has nothing to do with lasers. I will send you a pm.

Please, refer to my own self-conclusion on the topic in my other post, https://laserpointerforums.com/threads/newbie-here-will-looking-at-the-lasers-dot-for-a-minute-from-1-meter-with-no-glasses-cause-harm.104863/

Okay. I feel the need to give back. I will write this in my both two similar threads and will, of course, never double post again. I went to a thorough eye exam today. I have thankfully not suffered any serious damage, but my ocular pressure is rises a lot - it is 22/26 on left and right eyes...

Steve, That is an amazingly well written, beautifully informative reply that I would think should be linked up in a special section with commonly asked questions and perfectly composed answers to them. Now I know everything someone who is not looking to try it himself needs to know. And no, I...

Thank you for your kind understanding. I am from Bulgaria.

Guys come on! If this is some super sophisticated forum kept only for and by pros I will gladly make an exit. I was the first one to ask this especially for blue lasers, and am in no way connected to the user here. Anyhow, I am beginning to get tired of getting bashed like a little kid for...

Yeah, I understand. Mine is listed on those sites too:) If I remain in this, it seems I will need to look elsewhere for a quality laser:)

I did. It talks about not using lasers above 500 mw as they are Class 3b or 4 (but doesn't explain how those low wattage lasers cover a stadium); and also speaks about pulsed and continuous lasers, but this doesn't seem to be related to the class, and at the end it gets a mess and I don't...
