Eye protection products for airsoft should be able to withstand impact from a bb shot from any angle, at any range, from the fastest gun allowed on the playing field. There are documented cases of accidental eye injury occuring, even on organized fields, within an arm's reach. There are fields allowing sniper rifles firing up to 550 fps. That is why Dr. Airsoft testing is done with fast firing rifles at point blank range. Eye protection products which can keep a bb out under these conditions are appropriate for use while skirmishing.
Some tactical goggle manufacterers recognize that most goggles are vulnerable to penetration where the seal of the goggle passes over the bridge of the nose, between the eyes. Most (if not all) goggles that do not cover the front of the nose can allow a bb to pass between the side of the bridge of the nose and the goggle seal to strike near the eye. I have found this to be true on testing. That is why I separate airsoft eye protection depending on if the front of the nose is covered.
It should be known that there is no ASTM or ANSI standard currently for products dedicated for use in airsoft like there are for paintball. This makes it awkward for manufacturers to market eye protection products. There are a few manufacturers who have taken it upon themselves to establish their own standard which they consider appropirate for airsoft eye protection. In the absense of such product standards I have begun testing every product worthy of consideration and available for my use. Check the "Dr. Airsoft, Practical Testing" videos to see how the products perform.
