Well, in my opinion, it is ok to clean eyeglasses with contact solution. And so you do not need to worry about it. And in details, you can just first, take off your eyeglasses, and put on the table gently. And then, you need to spray the lenses with a cleaning solution made especially for lenses with anti-scratch coating and rub lenses with the same cloth to remove stubborn smudges if necessary. In that way, it will just clean the dirty objects on the lenses. Of course, you can just purchase lens cleaning solution at your optometrist or common drugstore. And it can be effective.
