That won't change the force transfered.

No it won't, but if the force is spread out there is still less stress on a single point. Ergo, less chance for the glass to break. Although this probably doesn't balance out the higher force of the paintball and the smaller impact surface of the BBs.

Don't have money to burn on stuff I'll just break. Also worth checking if others have any knowledge.

wont cost you any money if they pass.

is your vision or someone else's worth less then 30 bucks?

It might, you never know. Paintballs deform much more than airsoft bb's. It may equate to the same force per area all things considered.


Someone needs to try this out.

[dazbag]

Carolus Rex is right. The surface area is important. I play Airsoft as well. I can tell you, this glasses will hold up a Paintball without a problem. Sure u shoot an aeg about between 1J and 2,8J in regular playing. Depending on ur role, the field etc.
U wouldnt believe, how much energy can be transfered from a BB. This bb is hard and wont break. This isnt a Paintball that will just splatter and lose his energy. This little bbs can get threw ur skin, even in ur flesh from low distance. Airsoft can hurt like hell. U dont want to be hit from a 2.5J airsoft gun from 10 Meters.
But i would never recommand to wear this googles. There are open from the sides and most are not hold tight in there place. I mean, if u shoot a burst into someone, the first shot could take his googles off, and the next will hit his eyes.


Im playing in veckring/france on a field, where both is allowed. Same issue as u told already. But its more wild west there. All players more do what they want. Its kinda always a war between both sides. I play both, and i play with a dye i4 mask. Paintball players are more responsible. My Expierience and my opinion.
Why they use those glassed? Airsoft gaming is different. U can shoot further and shoot straight. So u actucally can use ur sights. Thats why they often use glasses, to use the sights. The dyei4 is one of the slimest mask, that kinda work with that. Forget this will all others Paintball Masks. I already tried a few. All are to big. Just didnt try out the save phace mask, but the dye one is more modern, better ventilated and got thermal lenses.

Holy hell guys, ANSI Z87.1 are ballistic rated, as in we use them in the military to protect our eyes from real weapons, they can take a hit from a paintball. The issue is that paintballs break and splatter around the edges of those glasses.

Does "ballistic rated" mean they can stop a bullet without breaking?

[Panda's Revenge]

Yes, but that doesn't mean your neck would snap from the sheer force of the bullet hitting your face.
I mean that thing travels at 1200 FPS or MORE and that force can seriously kill you just from impact, and not from the fragmentation.

But that's off topic, what's worrying is that there is no mouth protection.
I'd hate to see the day where one of them gets a mouth shot.

Quote

Protector failure criteria will be based on any of the following:
• Piece fully detaches;
• Device fractures;
• Penetration of the rear surface;
• Lens not retained; or…
• For the high velocity test, if any piece of the device sticks to contact paste or if contact paste is on
the projectile or on the complete device.

High Mass and High Velocity Impact forces to be tested remain essentially the same as the prior
standard. The high mass pointed projectile is pointed and weighs 500 grams and is dropped from a height
of 50 inches. The high velocity test uses a steel ball .25 inches in diameter that is fired at 150 feet per
second at the lens in the test frame.

The surface area is definitely important, airsoft BB's may not have as much energy, but because they don't break the collision would be inelastic, and the smaller area will focus the energy on a smaller point, which has somewhat of an amplification of the felt energy transfer, while in reality the force transferred wouldn't be any different.

A paintball breaks and shatters upon impact, meaning that the time of impact is longer, making the felt transfer of energy less than the airsoft BB. It also spreads out the energy over a larger area.

Think about cars and how they're designed in a collision. Newer cars are designed to smash and compress upon impact, which makes the time of impact or transfer of energy longer, making the felt impact less severe than an older car, which is essentially a giant chunk of steel. Older cars had much more severe impacts because the time of impact was much shorter because they were designed to stay rigid in a collision, making the transferred amount of energy happen in a shorter period of time, which amplified the felt energy.

I hope I was right with this or I look like an idiot.

I call bullshit on these magical bulletproof glasses until proven otherwise.

[TooTallNiCo]

Am I the only one who feels this is a Darwin Award waiting to happen?

About to go buy some airsoft goggles and make a 10 second video

thanks tootallnico

And yeah, ballistics glasses are not bulletproof. If they were then 2mm thick plastic body armor would be the standard for soldiers instead of plate steel or kevlar. Going up against a barret? 4mm and you're good to go...

Also, these guys often use .68 powderballs. Yeah.

So get this, you're not going to believe it.

Turns out the guy who runs the milsim group I've mentioned here is also the boss of 3D modelling at Weta (who made LoTR etc.), with 160 staff under him.

Turns out I'm a 3D modeller who's been trying to get in there for ages.

Turns out he heard about this thread and is seriously pissed at me, and now I'm probably not going to be able to get a job there even though they're hiring because I've pissed off the management.

Yay me. How the hell was I supposed to know? Life's an utter bitch huh.

*****

That said, it also turns out that they all wear sealed goggles and the unsealed glasses thing isn't actually the case. Given that sealed AS goggles are fine for stopping a PB, I guess I have far less of an issue with them than I did. Personally the only mandatory protection is eyes - ears and mouth hurt and can cause damage but to nowhere near the same extent.

What an ass.

[Uncas]

You can never be too safe. My next thought with glasses is that it doesn't matter if they can stop the paintball if they fly off your face any time they're hit. I would feel better about giving someone crap for a false safety breach than ignoring a real one. Apologising is easy, replacing people's eyes, not so much.

[NJC]

airsoft bbs .2 grams flying at 500 fps hit with .15 pounds of force
a paintball 3 grams flying at 300 fps hits with 1.5 pounds of force.
ten times the impact

and an almost completely unrelated topic for those who think paintball makes them tough, a lacrosse ball going 80 mph (which is a fairly normal shot speed) hits with 128 pounds of force

Lacrosse is an acceptable sport, yet paintball and airsoft are considered violent or whatever negative adjectives people think of. Genius.

Anyways, regardless of what the math tells you about BBs and paintballs, would you really want to take the chance with your eyes?

just tell him you were concerned about his safety and well being and if that doesnt work just call him an asshole and show him how getting shot in the eye really feels lol
