All throughout the books Harry's eyes are mentioned as looking just like Lily's. I think there might be something behind them...like a special power or something. It's rumored that we will learn more abour Lily Potter in the seventh book..maybe this will include learning the important symbolism of Harry and Lily's eyes. What do u think?
JK Rowling has mentioned that "But he has his mother's eyes and that's very important in a future book" in an interview.

All we can tell now is that there is a certain amount of significance, but how, we'd have to wait for the book.
