The number of times those get grabbed of someone’s face and stomped on will be greater than zero. And businesses will have signs for No guns/spyglasses.

I'm no lawyer and things vary by location, but clothing is generally considered an extension of the person and usually touching their worn objects constitutes physical contact with the person themselves. Doing so with intent of committing criminal mischief, vandalism, or felony property damage will get all of them thrown at you. If you hastily do so and happen to harm the person in the process (since you're naturally grabbing at someone's eyes, that seems like a serious risk), there's a good chance you'll be given an aggravated or felony battery charge instead.
