Green eyes and Blue eyes

In a remote island, people have blue eyes. People with green eyes can sometime appear but they have to leave the island as soon as they realize that they don't have blue eyes. One day a visitor says: "i see that some of you have green eyes". For the sake of simplicity, let's assume that the people can meet just once per day at a public Town Hall. What will happen after the visitor's claim?
