Many expensive sunglasses that money can buy are fragile. You drop them by accident and they crack. This pair of Japanese Self-Defense Force Sunglasses is different. These sunglasses look decent but will not fracture even if stuck at 171km/h (106mph) by a 6.55mm (0.3″) diameter object. They don’t stop a bullet and are not designed to. But they do not break easily either and offer 99.5% UV protection. It should go without saying that these won’t be cheap.
