Shit, shit, shit.

I did try measure out the divergence of my new DL 125 (while wearing the right goggles from DL).
But the beam hit my left eye from behind. Wanted to look close, cause through the goggles the spot is not very bright, then the beam went right over my ear behind the goggles and reflected from there into my eye. I was about 5 ft away.

Since this moment i see on my left eye everything "blueish". (3 hours now)
Is it possible, that only the sensitivity for red is affected?
I don't see any white or grey fields, nor spots or something else. It's just everthing looks more blue than on my right eye.

Any hints?

thx

A reflection from most non-mirrored surfaces usually won't exceed 10% or so. With a 12mW momentary exposure, I'm confident you'll see good as new in a few hours.

Wierd, I've never heard of seeing blue after a green laser damage. :-? I've been damaged myself - a window reflection from my nova x-85 into my right eye. I now all the time see a very faint dot if I look only with my right eye, butit's not too bad. Wierd that you don't see any spots or even grey fields.

Keep us posted about the development of this.

Oh, and welcome to the forum! :) I hope your future laser experiences will be better that this one.

Makes me confident. thx

hm, it is...
The color temperature is about 1000K higher compared to the right one. 5500K seem to be 6500K on the left. In other words, a white sheet of paper viewed with my left eye is very light blue.

I'll post later (everytime something noticeable changes - I hope it's soon ;-)

Thx

Your damage is not permanent. It is a significant warning about your safety protocol.

Since your entire vision field was effected, the strike was either over the optic nerve or your cornea was effected. If the strike is somewhere else on the retina, you would see more limited symptoms (like the "spot" that Lazerguy reports). If the damage was significant, permanent, and over the optic nerve, you would be blind in that eye. Since you only have an "after image", you will be fine.

NOW, BE MORE CAREFUL!

Peace,
dave

You've been right.
It takes a load of my mind.

Just compared again. It's fading...

The first shock is nothing really funny.

D'accors.
How do you manage this problem, I didn't think of?
Taping the glasses to your head? Wearing a hood? Or should I let my hair grow? ;D

Simply avoid placing your head so close to the beam, with it shining from behind you (although I personally prefer the long hair option). ;)

If you are interested in seeing the beam, control the reflection of the "dot" by shining it into a box or onto a non-reflective, dark surface, and take your goggles off.  You MUST still avoid getting your head so close to the beam, but if the reflection is controlled, you can take your goggles off safely.  When you limit (or eliminate) the brightness of the dot in the room, you can see the beam MUCH more clearly.

Put your goggles on again when you are ready to manipulate the laser again.

Peace,
dave

Or, to see the beam, just head outside and shine it into the sky or towards a distant tree. I have found that even with my 5mW green, the beam is definitely more visible outside than inside during nighttime.

How dangerous is it looking at the dot from 5 meters away on a none reflective (everything is reflective, i mean none mirrorish ;D) wall on a 120 mw green laser.

Without laser goggles? Very bad! I wouldn't even look at a 20mW on the wall from that close! Doing this would be seriously putting your eyes at risk.

Get a pair of goggles.
