Ok, "looked" is one of those words that can be changed for the same meaning.
Glance, Peered, Became lost, etc are good choices. Think to yourself how your character looked into someone's eyes. Sometimes that can help determine the right choice. Also combining sentences can avoid the problem altogether.
