Sorry, but this is meant to be a military sim - I've been on ops, and those effects aren't remotely realistic. There are a hundred and one physical and behavioural compensations which you make either automatically or intentionally to minimise the effect of blinding, motion, etc. When I loaded up Arma 2, the headbob was like a seesaw having an epileptic fit. In the game, these effects have a hugely disproportionate effect.
At the same time, in-game tinnitus and disorientation from explosions last for a few seconds, where in real-time they can be disabling or will last for hours. And obviously, there's also getting shot in-game...
The game is never going to be realistic, I'm just saying that the balance could be slightly better.
