Who said anything about "full spectrum laser glasses?" Man, all I told the people to do was use some protection. Back the f^^k off a^^hole!

Again, does it negate the validity of the advice in any way? If not, and since my statement is essentially correct, why then do you feel the need to criticize my comment?

Okay, all that may in fact be true, but does it negate the validity of the advice in any way? If not, and since my statement is essentially correct, why then do you feel the need to criticize my comment? If you claim it's because "commercially available" lasers typically don't emit UV...

*Lasers are sources of non-ionizing radiation (unlike x-ray machines, which produce ionizing radiation capable of knocking electrons out of atoms). Different types of lasers emit "ultraviolet radiation", "visible light", or "infrared radiation" —all are forms of non-ionizing radiation...

I don't know if anyone is still monitoring this post, but in case there is I've got a little experience with this phenomenon. I do experimental work every once in a while using a variety of common wavelength lasers and early on I noticed that I too get nauseous "whenever one is in use...

crashmiget, Although I do understand the concerns voiced here as well, I personally feel that the potential risks associated with discussing topics like this to our hobby are far out weighed by the enormously valuable information that such a discussion would most likely generate...

Thanks for the reply. Yea, I tried on that last post to include a quick hand drawn picture of it, but for some reason the link never made it in. Here it is though. lol Lightsaber | The Singularity Effect Me too. (No Mirror/corner to infinity! :) I'm betting it's actually pretty high though...

WOW! Awesome replies! And with that, I'd just like to say THANK YOU to all who have participated so far in this discussion. It's kind of funny. I've actually bought about 10-15 different lasers over the past year or so, but I can't seem to keep them around for any longer than a couple of days...

Hey, thanks for the reply! Even at 1 watt that's still a whole lot stronger than anything else that can be found easily online. I just went to the site where you bought your blue one. Pretty nice! I can't seem to find anywhere on the ad that says "it's" strength though. Do you know what it...

I mean, 2,00mw!!! :) Hello everyone. I was cruising around eBay today looking for a good price on a couple of inexpensive lasers when I noticed this. High Power 450nm Blue Laser Pointer Pen Military Light Beam Burn Match Paper 2W | eBay Is this real? Are these laser's really a full 2W of...

Now I understand the significance of the distinction between visible and non visible spectrum's of light, and the additional information they might provide. if I understand correctly, the implied context would be that if I were reacting to something affecting the "visual" aspects of the brain...

Well Airman, before I reply, I would like to just take a moment and rub your LEG a little if I may. :) To those of you who are unaware of what that flash is on bloompyle's beret, it is the emblem for the US Air Force's Pararescue unit. This elite force is responsible for risking their own lives...

As to the de-focus question specifically, the answer is "yes." Under conditions of 1 foot at fifteen feet, sustained exposure greater than 15 seconds, 532nm, 100mW= nausea

If I even step into a room where a laser is in use I become almost immediately nauseous. The way I have to use them is at very brief exposures, and well thought out configurations because for me every second counts.

When I ran into this thread a few weeks ago, it was because I was looking for a similar thread I had commented on a while earlier. When I noticed I did not have a comment, (but I did have an account) I figured I'd leave something. I'm not sure if the original poster is even watching the thread...

Pretty much, yes. I've had various commercial (novelty) lasers over the years, but probably never really played with one more than the average person does with a cat. Until a few years ago when I started working in the fields of high energy, and plasma physics. Since I needed quick, easy...

Actually, the person is on to something here that isn't as simple as it seems. Both my daughter and myself suffer from the same problem. Mine is triggered by everything from the mid 400 to mid 600nm ranges. There is not a lot of real info on this though, which I find so strange since the effect...

I've go new set of lasers coming in the next few days. I'll try out a bit of Dramamine or something similar, before I check them out. I'll post my results.

Nope! Not a flashlight. I just shined a pocket LED (4.5v) right into my eyes for a second. Even waved it around a bit. Wait....? Yep! Starting to feel a little something now. Just a little bit though. I'm betting if I'd done it longer, I'd have had more effect. Okay, let's go back a little...

My daughter and I both have the same thing going on. Here's the deal though. I was adjusting the focus on my green 5MW eBay special when I started noticing this problem myself. I was thinking it must have been from earlier when I forgot to wear my glasses, but still wanted to see if perhaps I...
