The idea is when your in a open vehical in a environment that has smoke or sand flying around in the air, your vision is effected by it and becomes temporarily impaired and blurred out becuase you have some foriegn substance in your eye.
Flying at high speeds in a helicopter sitting next to a open side door, some sand might fly in and effect your eyesite.
simply using the BF2 SF Gas mask as clear googles to be placed on your player by a tap of a button (default settings. 8 ) the mask appears on the players face.
just change the way the mask looks in 3rd perspective to look like a pair of tactical sand goggles.
the goggles are already placed on some of the player model's helmets, why not simply use them?
these are just ballistic googles.
putting these on will keep the players vision normal and visible from the airborne particles, dust and sand.
without use of this, player will experience the surpressed vision or the simple tear gas effect.
