Player swings his arm trying to get leverage while jumping for the ball. The arm is loose, the hand open but makes contact with the opponent's eyes. Totally accidental, but careless striking nonetheless, free kick only required.I am at a loss as to how you can somehow believe a player can carelessly strike an opponent. There is no measurement bar for striking an opponent off the ball. As I have said the only one that carries any kind of barometer is pushing an opponent. You can quote definitions from the book all you want, yes VC is a foul but you can't treat it the same as a tackle. The simple question is has the opponent struck or attempted to strike another player/official etc, if the answer is yes then it's direct free kick or pen and red card, simple. I hope that helps.
