Hey all,
Im looking to replace my current eye protection solution (mesh goggles over my eyeglasses) with a one piece solution, designed specifically for airsoft/sport if possible.
the two options that I see are either:
-Glasses with polycarbonate lenses and frames which fit around the face
PROS
CONS
-Normal protective goggles with prescription inserts
PROS
CONS
Has anyone had any experiences with these solutions to suggest any other notable PROS or CONS to consider? or is there another eye protection solution to consider?
BS EN 166 Ratings and Energy
IF my research serves my correctly, the impact rating (BS EN 166 F or B )is tested using a 0.86g steel ball fired at the lens or frame (or both) at a certain speed, 45m/s for the F rating and 120m/s for the B rating. my Maths tells me that this is 0.871j to be rated as 166 F and over 6j to be rated as 166 B. to add some perspective, a 0.20g bb at 350 ft/s carries a little over 1j of energy, and a 0.20 at 500 ft/s carries 2.323j.
this means that BS EN 166 F eye protection is not actually adequate for airsoft, as the kinetic energy carried by a BB out of a sniper rifle or even most AEGs is significantly more than the requirements for the standard. And on the other hand, BS EN 166 B is massive overkill. Eye protection is not limited to these requirements however, and there is no reason that a pair of BS EN 166 F glasses cannot survive a 2 j hit, just because it has an F printed on it. i havent seen any tests, but if i read correctly, polycarbonate lenses can be used to create eye protection that can stand up to anything an airsoft field can throw (or shoot) at it, though i would be a bit nervous to pay £100 for polycarbonate glasses just to break them when testing, much better to get the seller to assume that responsibility, especially when buying from somewhere that claims to provide eye protection for airsoft.
now, any eye protection i use will get a point blank shot from my own AEG before i trust it on the field, but prescription eye protection can be expensive...
Thanks for reading guys

-Glasses with polycarbonate lenses and frames which fit around the face
PROS
- lightweight
- minimal fogging
- may be more comfortable
CONS
- Limited to BS EN 166 F (rated at just over 0.8j, see below)
- not quite as protective as fully fitted goggles
-Normal protective goggles with prescription inserts
PROS
- Better seal around the eyes
- More secure fitting (Generally)
- can be rated up to BS EN 166 B (over 6j, see below)
CONS
- likely to cause fogging, due to two extra surfaces to cause condensation upon
- more bulky and heavy
- may be harder to use certain weapon sights
Has anyone had any experiences with these solutions to suggest any other notable PROS or CONS to consider? or is there another eye protection solution to consider?
