What eye protection is safe for airsoft? (EN166 explained)
Last updated: 18 July 2026
this is the most important post on the site. if you only read one, read this one.
everything else in airsoft is fixable. a blown gearbox you just buy again. an eye you don't. and airsoft eye injuries are nearly always preventable with the right protection, so it's a real shame when it goes wrong.
the short version: you want a fully sealing goggle with lenses that meet EN166, at minimum the F class for low-energy impact. no shooting glasses with open sides. no ski goggles. no swim goggles. no hardware-store safety specs.
what EN166 is
EN 166 is the European standard for personal eye protection. it's not one test but a set of requirements, and the results get marked as letter codes on the frame and on the lens.
the code that matters for airsoft is the mechanical strength:
| Marking | Test | Meaning |
|---|---|---|
| no letter | minimum strength | not enough for airsoft |
| S | increased strength | not enough for airsoft |
| F | low energy impact | 6 mm steel ball, 0.86 g, at 45 m/s |
| B | medium energy | same ball at 120 m/s |
| A | high energy | same ball at 190 m/s |
F is the minimum for airsoft. the F test uses a projectile that's heavier and carries more energy than any airsoft BB you'll ever be shot with at legal site limits, so a genuine F-rated lens stops a BB comfortably.
B and A are certified tougher. nice to have, but not needed. F is enough, as long as it really is F and not just a sticker.
watch where the marking is. both the frame and the lens need to be marked. an F lens in a frame that can't take the hit still gets punched into your face. you're looking for something like EN166 F on the lens and on the frame.
a note for readers outside europe. EN166 is a European standard. if you're in the US, the closest local equivalent to look for is ANSI Z87.1 on the frame and lens. i'm not going to pretend to know the exact class breakdown of every national standard, so check what your own field accepts and buy to that. the principle is the same everywhere: a fully sealing goggle, certified impact-rated, marked on both frame and lens.
STANAG 2920 and V50
on better airsoft goggles you'll also see references to STANAG 2920 with a V50 value.
that's a military ballistic test. V50 is the speed at which a standardised fragment penetrates in 50 percent of cases. the higher the V50, the stronger the lens.
brands that quote this, for example ESS, Revision or Oakley in their military lines, test at energy levels far higher than airsoft ever reaches. if a goggle is STANAG 2920 certified with a decent V50, you're more than covered on strength.
it's not necessary. it's a very good sign that you're dealing with a serious manufacturer.
why shooting glasses aren't airsoft goggles
this is the mistake i see most often, and it's a dangerous one.
shooting glasses or safety glasses with arms have open space at the sides, top and bottom. on a shooting range everything comes from the front. in airsoft it comes from every direction, ricochets come off the ground, off walls and off trees, and they travel up underneath your lens.
so a pair of glasses can be perfectly EN166 F certified and still be completely unsuitable for airsoft, because the certification is about the lens and not about whether there's a gap next to it.
what you want is a goggle that seals against your face. a closing rim all the way round, usually foam or rubber, with an elastic strap. no gaps.
i use this as a test: hold the goggle up to your face and look for any light leaking around the edge. if you see light, a BB can get through.
mesh goggles: the warning
mesh goggles, with a metal grille instead of a lens, are popular because they don't fog. there are two real problems with them.
fragmentation. a BB that smacks into a metal grille can shatter. those fragments are smaller than the mesh and can pass through it. that's exactly the scenario the protection exists for.
they're generally not certified under EN166 for this use, because a grille is by definition not continuous.
some fields allow mesh for the lower face but not for the eyes. i'd advise against mesh for the eyes. for the face and mouth it's fine, it's actually a good solution there. i cover that in my post on face protection.
what else to look at when buying
full seal. already mentioned, but it's the most important thing after the certification.
ventilation. goggles that don't fog are goggles you keep on. and goggles you keep on are the safe ones. look for dual-pane thermal lenses or a built-in fan. i've got a whole post on anti-fog that actually works.
compatibility with a lower face mask. big goggles and a lower mask sometimes fight over the same space, which leads to fogging or a poor fit. fit them together.
glasses wearers. pick an OTG model (over the glasses) or a goggle with a prescription insert. contact lenses are an alternative but a lot of people find them annoying with dust and sweat.
interchangeable lenses. a clear lens for overcast and indoors, a tinted one for sun. handy but not needed to get started.
price range
expect to pay somewhere around 50 to 90 euros for something you can actually trust. brands you'll see a lot in the airsoft scene are ESS, Revision, Bolle, FMA in the budget segment and Oakley at the higher end.
under 30 euros i get nervous, unless it's a known brand on sale. no-name goggles off a random marketplace listing for 12 euros you just shouldn't do. that's the one place in this hobby where cheap really is expensive.
maintenance, because everyone forgets this
scratches weaken polycarbonate. a scratched-up lens isn't just annoying to look through, it's measurably weaker. replace your lens when it's scratched.
store it in a pouch. not loose in your bag among your mags.
clean it with water and a microfibre cloth. no aggressive cleaners, they attack the anti-fog coating and the polycarbonate.
replace after a hard impact. if a BB has hit it hard from close range, check for hairline cracks. when in doubt, replace.
rules on the field
outside the safe zone your protection goes on and stays on. always. even when it's fogged, even when you just want to grab something out of your bag, even when you're only walking to the toilet.
goggle fogs up mid-game: call it and walk to the safe zone, or take the hit. don't lift it to wipe. most serious airsoft accidents happen at exactly that moment.
see someone with their protection off outside the safe zone: shout CEASE FIRE or BLIND. everyone stops shooting. that's not overreacting, that's exactly what the command is for.
