No, the glass eye wouldn't have been a problem unless he was wearing one of his designer eyes or his patch. But now you made me snicker for a totally different reason. Dad had a glass eye. He also had false teeth. At night, his teeth went in a glass dish in the medicine chest and his glass eye went in a shot glass on the next shelf up. Imagine being 4, climbing on the sink to get your tooth brush, looking in the medicine chest and having it not only look back at you, but smiling at the same time.
