Are you trying to make it look less obvious that the subject is wearing glasses? Even if you avoid glare, there is always refraction and the curvature of the eyeglass lenses to worry about, especially if the shot isn't straight on. Wearing glasses is a choice for many people and it definitely affects how they look, so they might not be entirely pleased if you eliminate the glasses effect. It was a very long time ago, when anti-reflective coatings weren't very good, but for my wedding, our photographer gave my best man and myself empty frames for the formal portraits. Even without the bags I now carry under my eyes, there is something about the way I look in these photos that doesn't look natural (to me at least).
