Eye protection question

[deezdrama05]

Hello all, My question is about laser radiation and the hazard of it to your eyes. Should I wear eye protection when doing mods on a 30mw laser or while doing meter tests? I have never looked anywhere close to the beam but it seams like when the laser dot is on an object close to me and im messing with my laser my eyes hurt after a while.

 

[senecaripple]

ditto, my eyes hurt too it needs a couple of days to recoup. still waiting for my goggles from wicked lasers i ordered a couple of weeks ago before i mess with it again

 

[deezdrama05]

how much can I pick a pair up for? how powerful is your laser?

 

[flashlight]

I've just ordered a pair of goggles from here but not got them yet so can't tell you how good/bad they are but they seem pretty cheap though.

They are what i've got for now. Picked up a couple of pairs actually. No use having protection for yourself and not your audience. Great for 532nm, no good for red lasers. Can't tell if they are any good for infrared.

I bought a pair of these. They work really well, and its cool to walk around with them on, everything looks so different.
They only block 532.
My red 99 cent one shines right through, but if i look at the dot from my green pointer, it looks like the smallest little white thing, like the tip of a pen.
I got them for about 20 shipped to the US, and they came pretty quick.

 

[deezdrama05]

so these red colored goggles work for green lasers?

 

[DaFiend]

yes, but not for red.

 

[deezdrama05]

cool ill up some money for a pair when I aint broke untill then ill further to blind myself /ubbthreads/images/graemlins/sick2.gif

I reccomend laser eye protection when dealing with anything greater than class 3a exposure. Yes, if you open a 3a 532nM pointer down to the diode you are far exceeding 3a exposure limits. /ubbthreads/images/graemlins/wink.gif

I may be paranoid, but I am a paranoid person with 2 good eyes. Its real hard to get a replacement set from what I hear.

How much did you pay for that glasses? 10 pound?
Sorry but i'm not really familliar with ebay.

Yup that works out to about US$20 before shipping. You have to contact the seller first to check shipping cost to your location. I paid about US$28 for shipping to Singapore (S.E. Asia). You can use VISA or PayPal to pay in the seller's designated currency .

The dot from my leadlihgt 30-50mW did hit me in the eye from a reflection of a mirror !
I did then notice a tiny tiny white spot on my eye.
The white spot did stay there for 2-3 days, then it did go away :O

2 days ago i was playing with my laser scanner and my 150mW laser, then suddenly when the scanner was making a tunnel effect (with me inside it) i did get hit by the laser once more time /ubbthreads/images/graemlins/blush.gif
And this time the laser was damn bright, almost like somebody did punch you in the fase!
I did notice the day after this tiny white spot on the eye.. today i can still se the small white dot there, but it`s starting to go away and getting smaller now /ubbthreads/images/graemlins/blush.gif

I indeed ned googles, but the googles are way to expencive /ubbthreads/images/graemlins/blush.gif
i will try to take more care in the future...

the green beam is just soooo sweeeeet.... arhhh..

Get the ebay ones if you're doing green lasers, the one linked there. Especially if you're seeing white dots /ubbthreads/images/graemlins/icon15.gif. Anything has to be better then nothing!

Sears is selling some red plastic glasses with a laser level .$14.95
prob good for green block only.
They are selling it as a "laser enhancer"
if anyone experiments with these i would like to know the results.

 

[K-T]

Could it be that "laser enhanced" has nothing to do with protecting you from ceratain laser rays but more with some fancy production process?

I suggest to only buy quality googles from well known sources, your health and eye sight should be worth that money! /ubbthreads/images/graemlins/icon3.gif

 

[DaFiend]

laser enhancer makes me feel like the beam will actually do more damage to my eyes /ubbthreads/images/graemlins/wink.gif

 

[14C]

The only thing those Sears goggles do is enhance the beam visibility by color contrast. They will provide no eye protection for any color laser.

As K-T says above buy the best quality goggles you can find. And make sure they are rated at the proper wavelength(s). Especially if you are using higher power units of any color. Goggles may be expensive but eyesight is priceless.

How much did you pay for your lasers?
How much do you think your eyes are worth?
What if you get hit again & the white spots never go away?
Do you still think goggles are expensive? /ubbthreads/images/graemlins/confused.gif

Any red plastic or lens material will attenuate green light. Try red cool-Aide. The problem is that green lasers make red light too. These hopped up pointers can have more red in the beam than green. If your playing around inside a dpss its much worse.Better safe than sorry. Royal Army glasses are probably OK for general 532 use. But how are they in IR ? Try your TV remote thru them. The remote is probably about halfway from 808-1064. Does it conrtol the TV normally. Or is it hard to get it to work even point blank.
If you are working on green dpss laser's you need triple coated glasses. They cost alot.Thats one less laser your not gonna buy. But this Forum wont be much fun when you cant make out the text anymore.
