Apparently, lasers are being used offensively by Antifa rioters. They've been used against the police and I just read where they used them against an individual.
Does anyone know the wavelength of the lasers that would be used and what eye protection would be appropriate? I see quite a range if offerings on Amazon, but they seem wavelength specific.

I think that anything in the 45acp to 9mm wavelengths would be quite effect against even a large number of lasers. Might start with a pound of something in the bear spray wavelengths first just because the cost is lower.
 
Im curious about this as well.....

I have a 5w that is blue/purple(450nm). That will burn skin at 25 yards. It is nothing to be messed with. I use a 40w And a 60w for engraving metal and usually only run them at 25-35% power.

The little handheld 5w will light matches at 15-20 yards. (It is the most powerful laser pointer I have ever seen personally). It is about the size of a sword grip.

Problem for eye pro from lasers is there are 3 types red, green and blue (and not as likely but somehow some idiot could get a UV or IR one) which function at different wavelengths. The red is typically about 640-650 nm, the green is typically about 530-540 nM and blue is kinda wider spread but 405-450 nm. The problem is lenses are not coated to cover that wide of a spectrum to cover all three ...

IN GENERAL laser safety glasses are categorized by laser type and wavelength ... and power when you get into the hotter ones. The blue and green can kinda sorta be protected from by the orangish argon type lenses ... red requires a different coating that a lot of the time is a greenish blue color ... but I don’t know of any lenses that protect across all 3.

From what I’ve seen on TV most rioters are using green ... and by the level of light and size of beam they are not using cheaper pointers like those for presentations ... they are not at the 5 mW green lasers (which is like Crimson Trace level) ... they’re running 50 mW ... 100 mW or more which will burn skin at a couple feet, pop balloons at a few yards or damage the eye at a couple hundred yards (at close up range burn the retina quickly). The higher powered ones are a couple hundred bucks and fairly large because a larger power source is needed ... we aren’t talking regular batteries here think Makita not Duracell. As to blue lasers which are far rarer they can go farther up in power and so does damage with it. Protection for the green and lower blue could be $25-$30 pair of safety glasses but if it’s a 150 mW green or blue laser then further coatings really are needed.

Truth be told the people who fall victim to laser attacks will likely see floaters for the rest of their lives ... and with possibility they’ll get worse as their eyes age.

Which should fall in the "great bodily harm" category of self defense.

You don’t, but you don’t need to, you are being attacked by a mob.

That will get you thrown in jail instantly. You get laser flashed by an unknown person in an unknown place so you open up on the nearest bystanders (who clearly don’t have lasers)? Good luck with that.

In Chile, there was a good video of mob-lasers being used to drop a drone (which I support).

Interesting. Do you support individuals using lasers on drones in suburbs? Or, do you only support mobs doing so? I'm just doing a consistency check here.

Maybe some schadenfreude leaking here, but it might have been interesting had the drone pilot dived the bird down to crowd level: how many of those peaceful protesters would have followed it down with the beams still on?

Disclaimer: none of this is to be taken as an endorsement of Chilean political leadership.

Lasers are nothing to be trifled with. Small inexpensive ones will damage your eyes. Larger more expensive ones will blind you, instantly. I use a few lasers everyday for my business. Like Fubar said, they are dangerous. They can be used as weapons to cause serious bodily harm. I will take a few photos of the 5watt handheld I have in action and put them up later. The lasers I use for work are UV and invisible but still cause damage if you look in the direction of them.

Any shooting will get you thrown in jail. Front man in the mob grabs you and you shoot him because you’re afraid for your life, I’d bet on walking home. If nobody is within striking distance then you probably had the option to retreat and should do so.

Perhaps a VR headset linked to a GoPro or mobile phone so your eyes never get direct laser exposure.

A laser of decent power will quickly burn up the CCD in a GoPro for sure and likely any phone also.

ETA ... porch pirates have been known to use lasers (and higher lumen lights) to blind Ring doorbells.

I checked their site but did not see the ability to protect against lasers beams. They look very cool though and do look strong. Maybe I missed something there...

Scroll down. Some of their Stingerhawk line says they protect against lasers. But, again, what happens if the “protesters” use a different laser than the ones your glasses are rated for? Edit: I guess the FT-2 would be the logical first purchase

So this is a serious threat. Can anyone link to an affordable set of protective lenses? What about stacking lenses to cover red/green?

I think I’m pretty much anti-drone and I think I’m OK with anyone pointing a laser at any of them at any time.

I haven’t really given substantial thought to the subject, so I could be swayed with a good counter-argument.

Yes but your eyes will be safe, good to use older obsolete phones. The phone and GoPro will pick up the UV laser beams.
When they use the lasers in an aggressive way, law enforcement needs to deploy the LRAD to stop them.

Nah ... just issue then more powerful lasers ... mounted on less lethal weapons ... and let them lase back.

Why anti drone? They are great fun and harmless. The only drones I worry about are government swarms. There is no defense. -Mr. Miagi
 
So if these lasers can cause permanent blindness, which is serious bodily harm, what level of force is acceptable in defense? Thinking more in terms of police.
 
Momentary stray reflections from 40-50 mW and up are enough to blind or damage instantly. Co-worker of mine (when I was in the fiber optic transceiver design business) pulled a live 100 mW IR fiber out of a connector; the beam swept across a metal surface, bounced up into his eye...and boom, blind in that eye. We assembled a 100W blue laser source at work for a program...scariest thing I’ve ever worked on. We had safeties and procedures out the wazoo. No issues, but we were rabid badgers about safety.

So to me this is a big deal. For safety, specific PPE (mil level) will probably be needed. I certainly consider this to be in the grave bodily harm category...anyone in the judiciary/etc who doubts it should be volunteered to stand against a wall, eyes held open, and allow a 5W laser to merely flick across said eyes. No? Then you aren’t allowed to question the response to an IDed individual carrying out such an attack...for an attack it surely is.

So what's mil level PPE for the situation?

This is mine 5w handheld at about 35 yards on a tree. It is very visible in broad daylight. If it were to hit you in the eyes, you would have some serious issues.

Hmm... Mount that to a rifle stock with a scope or other sighting device and you have a serious offensive/defensive tool.
