50mw laser eye damage

joshshermannn1 · Jul 14, 2011

i let a friend of mine play with a 50mw green laser of mine(with glasses) and when i came back, glasses were off and he had flashed it across his face on accident i assume. what damage could this cause?
it has a very small beam diameter.

joeyss · Jul 14, 2011

uh those very small beam ones are nasty.... did he see it hit his eye? If so tell him to get it checked out.

joshshermannn1 · Jul 14, 2011

Direct contact for a few seconds.... How bad is it? He's getting it checked out tomorrow. Is it fixable?

joeyss · Jul 14, 2011

Probably not.....why did let it hit his eye for a "few seconds"???

Mohrenberg · Jul 14, 2011

Did it hurt? Cause I hear stupidity doesn't hurt at all.

How old is your friend anyways?

joshshermannn1 · Jul 14, 2011

he's a very stupid 18 year old....
and i dont know....
@mohrenberg hahaha

[/sympathy]

18 years old. Old enough to be accountable for his own actions. This is his fault for being stupid and I feel no sympathy for the damage to his eye. ESPECIALLY if you furnished him with a pair of safety glasses which he simply took off. Does he happen to look down the barrel of guns as well?
I guess he can only hope the permanent blind spot is in the corner of his vision and not directly in the center.

Furthermore, I just bought my first pair of laser safety glasses about a month ago. I played with lasers for almost 3 years with no mishaps. The fact that he managed this in a matter of minutes is just astonishing.

hopefully he's learned his lesson, after her gets back from the eye doctor ill report the damage.
can eye surgery be helpful at all?

You mean he just aimed the beam straight into his eye & stared at it for awhile?.....
Could he have been drinking perhaps? Not like I haven't seen that level of stupidity tho.
Hell at least it wasn't a 445.

i dont think anyone would be stupid /pain tolerant enough to shine it directly at your OWN eye, more like milliseconds or a 'flash over'....

I know someone that looked down the barrel of a gun to see if the pin was working

He shot it and miraculously it missed his head... Only to hit an oil tanker.

Pretty horrifying but not surprising. I have found that most people think lasers are toys.
After a serious safety talk with a 25 year old computer programmer, I placed the 532nm in his hand.
Immediately, he began to wave it around the room at everything in sight, including mirrors.
I'm not sure why people don't get it. Nowadays I hand my lasers over to nobody.
I hope your friend is ok.

Same with my coworkers. Sure, you can trust them with your life, but don't trust them with a laser. They simply don't get it.

I think there is no natural feeling that a laser is dangerous thing. Thus point here and there, upps it hit me :undecided:

Anyway back to the topic starter:
Did he feel anything after the laser hit his eye(s)? If it was only a nearby eye (no direct hit), he'll be fine.

The next time don't give any laser to anybody, like your wife (or a girlfriend) :wave:

^ I find girls tend to actually be scared of lasers blinding them even if they don't hit anywhere near the eye or face. I guess it's just like them and spiders ....most of the time.

I show my friends my 5mw green pen and tell them it can cut metal, then shine it on their hand to see their reaction.

On a more serious note, I've seen a couple of people walk in and say that their eyes have been hit by lasers, under most circumstances it's a 1mw red laser and I've never seen a case where that did anything except excite the cones in their eyes.

Whenever I hear that somebody has a case with eye damage, I slip in and ask them how they got the damage, the WORST was from a 100mw green laser and he ended up fine, but other instances a 50mw gets somebody and they get a blindspot. It really varies from person to person and because every situation, duration of exposure and distance is different, we can not be sure to say.

I can say from personal experience however that if you're just looking at a bright dot (68mw here

) for a while, if you go turn off the laser and turn the lights on, your eyes might hurt for a couple of minutes, that's just irical response.
