When i was a kid i got my hands on a 100mw green laser decided to take it outside during winter i thought its batterys were dead and pointed it at my left eye. i lost about half off my eyes accuracy and now i see very badly with my left eye and depend on the right eye.

Had a 'legal' limit blue laser and a slight reflection off shiny metal gave me a spot in my vision that didn't go away for years..😐❤️🇬🇧

Treat every laser as if it were on. Never point a laser at anything you do not intend to blind. Keep laser safety goggles on while laser is in use. Keep power disconnected from laser until you intend to use.
-
"Do not look at laser again with remaining good eye" was the warning sign on a laser equipped device in one of my workplaces.😉
-
"Lazer beams are always an eye hazard, especially the invisible ones in this video..." puts on safety goggles and carefully peeks at the screen
-
the worst part about those lights are: it typically points at your front of the house where you walk past it (and potentially directly at it)
-
Cold sensitivity is part of the reason I used a 520nm direct diode when building my astronomy laser. VERY expensive, but it was absolutely worth it!

Don't use a green laser in the cold! -Blue laser
-
Yes I will!

“Remember... if it comes with a warning label, somebody did it.” — Stephen Colbert My first slot-load DVD-ROM drive came with this label: “Do not use the accompanying tool to manually eject any disc from this drive while the disc is still spinning. Doing so may cause a variety of serious injuries including decapitation.”
-
Honestly, I don't trust those lawn laser shows because I'm scared they're gonna make me blind if they shine through my window.
-
This is actually really scary stuff. Random people buy those green laser lights for Christmas all the time and completely and unknowingly carry an extremely dangerous weapon. And they don't even know it's on.

I burnt my retina in the 70’s looking at eclipse of sun with no eye protection. I can’t tell how much hassle it is only having 1.5 eyes. Play safe kids!
-
Wow, I didn’t know green lasers could make infrared when cold. I took a laser safety training course in college, we were very careful about locking the door, taking off all jewelry, putting a filter in front of the laser till we had it aligned, etc. lasers are scary!
-
Intersting. I've got two of the green 5mW pointers like you show here. One functions correctly. With the other, it appears that the green lasing went out on it; not sure if it is due to a misalignment or whatever, but you can see inside the bezel that there still is some activity going on. Not sure I would have guessed it could still be lasing in the infrared spectrum, but I've seen enough here that I think I am going to permanently disable it.

Today I learned Europeans have upside down refrigerators.

"Do not point lasers In your eyes" Me who does it thinking the battery died: 👁️👄👁️
-
I wish i knew this when I was a younger. The amount of times I have looked directly into a laser beam is unbelievable. When my green laser was dead flat I would see a red light so id look directly into it. But now I am a lot safer with lasers. Especially knowing just how powerful and dangerous they are
-
This is pretty spooky to see. I had a friend with one that we were messing around with one late on a cold night. I don’t recall looking at it directly ever but it was only working when it was warm. Worrying to think I could’ve damaged my eyesight
