In real life, one would not be able to aim while using night vision (unless the scope is a special google compatible scope) because the goggles would not fit the scope. In Arma 2:OA certain weapons allowed aiming while using night vision because they had specific scopes, while others didn't, so I believe Bohemia will probably add special scopes later during development.

If this issue is still relevant in current dev build, please re-post.
