The lenses on these slick, heavy-duty sunglasses are officially endorsed by the Japanese military because of their pretty-much-unbreakability; they've tested them by firing small objects at over 100 mph and dropping heavy iron rods on them, meaning you can finally learn to juggle knives!
Slip on these shades and you'll feel part of the army. The Japan Self-Defense Force Sunglasses have been officially endorsed by the Japanese military and not only look super cool, but are ultra strong as well. The lens will not fracture even if struck at 171km/h (106mph) by a 6.55mm (0.3") diameter object, nor do they shatter if a 500g shaft of iron is dropped on them from 1.27m! While they can't quite withstand an actual speeding bullet you get the idea!
