What does it mean if this handsome dude looked at me with happy glowing bright eyes?

I was talking to a fireman and he was really handsome. I had a crush on him. I noticed that his eyes were very oddly bright and face glowing... just wondering if he detected my attraction. Its definitely not how a normal person's eyes would look. None of the other firemen around him had the same eyes.
