Hey, Im new here and have some questions.....

[Da_Dude]

Hey, just a few questions...
1)- At what MWatge do you NEED eye prtecton?
2)-At what MWatge does a laser need to be at for the beam to be visable?
3)-Just for refrance, about how old is the majorady of the members here?  
:-/

 

[me_too_lazy]

1) 50mW +
2) 5mW +
3) 12-40 ish

my estimates at least

 

[Da_Dude]

GAH !!!!!!!!!!!!!

Read the safety section...sunglasses will kill your eyes...might as well remove them, and put them in the microwave on high - or better yet, popcorn setting !

Thats why I came here anyway.
I wanted to ask the experts.
So...Welding Gogles?

Nope same problem.

There's only one substitute for good laser goggles - better laser goggles.

Sorry, no shortcuts here. Imagine being blind and looking back in time, regretting you didn't spend a measly $50 on goggles to save and keep your vision. Sure its not a likely scenario, but its not a gamble I, for one, would dare take. Make no mistake though: anything but quality laser goggles IS a gamble.

AND....make sure to read up i nthe SAFETY area some ....it's almost required reading if you want to stay healthy...not being rude by parotting myself, just trying to hammer in a point....

 

[Da_Dude]

And I get it.

*Imagine being blind in one eye

*Warning: Do not stare into laser with remaining eye.

Yeah, sure, probably not gunna take out two eyes at once. Still though, I'm making a point dammit!

 

[Da_Dude]

I beter get looking for a good pair(of gogles )
Any recomendations?

it should be pointed out that for a 5mW beam to be nicely visible, it needs to be a green (532nm) beam. a normal 650nm red will not have a visible beam, and a 635nm red has a very faint beam, and i've heard people say that a 5mW blue (473nm) will also be visible, but...green's obviously optimal. and Da_Dude - nice images of link in your signature!

It happened to me too at age 7 and my eye had to be removed, but I did it to myself by accident with a knife. If there is anything good about it, it did happen when I was young and as I grew a little order I adapted quickly. Needless to say I am very careful with lasers and everyone else should be too. Do not skimp or look for a cheap way out of good eye protection.
