Protection for eyes

[Switch]

Switch I don't think it's very wise for you to be telling people who might not have as much experience as yourself not to buy goggles if they trust themselves and their common sense. I think that's very poor judgement on your part, while i have faith that you know what your doing, others especially people newer to lasers don't know what to shine at or what not to, besides the obvious don't look directly into the beam.  
I think you should encourage people, especially one's just getting into lasers, to buy goggles and stress the importance of wearing them.  While i do sympathize and agree with you especially with greenies that half of the fasination with them is the gaze of sparkling green that you can cleary see in the air such as outside, but especially for burning or inside "play" goggles should be worn until they understand more what their dealing with in the relm of high powered lasers.

If you told me 6 months ago that a handheld pen-laser can burn through a CD case I would've been like "WTF? ". A month after that I built my first DVD laser and begun getting into lasers.....5 months later , my sight is yet to be impaired in any way.What I'm trying to say is that I'm no expert and I don't have and never had any special training ....I just used my common sense.So if I can do it, I don't see why others can't.They just need some information and steering in the right direction.

I'm not saying that eye protection isn't a MUST...I'm just saying that you can safely shine a 30mW laser in the sky, or indoors , at non reflecting surfaces as long as you are careful without wearing glasses all the time.

thanks for information!
Im not gonna go around shining my laser off mirrors and into my face, or anything, im not a complete dumbass... ;D

But, im stuck between getting a 20mw or a 30mw
Im not gonna get glasses tho

BTW can i shine the 30mw or 20mw on white walls and still be safe, or will it reflet off white objects?

If you're not gonna get glasses, stay completely away from burning(unless you keep your eyes closed ). Also be careful at any shiny or white surface.Even some smooth furniture,a plastic bottle, water surface, a window, anything metal or glass, etc. can cause an undesirable quantity of light reflected back at you.

Yeah, and DX lasers don't have the best IR filters either. I perosnally dont use goggles for pointing the laser around, because its usually outside with no chance of a significant reflection. I don't have any goggles yet, but i usually find something to use, like welding goggles. I am getting some goggles soon though, to me they are a big prt of being a laserist. Anyway if you decide to shine it in your eye, its not our problem, you blind yourself and have to live with it for life, we cant monitor what you do.

They're your eyes. Enjoy them while they last.

Well if i get a 20mw, its not much more powerful than a CORE which is usually 5-10mw

If u guys have a website where i can buy a 15mw it would be the best, for $45 or under, that has an IR filter

*can u see the beam of the CORE when ur in a room with the lights turned off?

Yes you can see the beam of a CORE in a dark place. I suggest you get that first, learn where to and where not to shine it at, and then get the DX 30. I haven't heard of anybody here who has worn goggles when using the DX 30. I think it's pretty useless to use it inside. It's much more fun to use it outside at night (just be careful with planes or any other moving thing) to look at the beam. In my opinion you don't necesarily need goggles to use a 30mW laser, it doesn't burn anything, so it's pretty pointless to wear goggles just to stare at the dot. ;D But you do need to be careful when using it so you don't get hit by any unwanted reflections, that's why I think you should get a CORE first, or just a cheap red laser, then get the DX 30 and try to use it outside most of the time.
