Yes, it is true that a woman's beauty is reflected in her eyes. I think this also applies to men.
William Shakespeare once said “The Eyes are the window to your soul”
When you look into the eyes of another person, really look, you can see joy, mischief, sadness, sorrow, sympathy love and hate. This is why we often distrust those who will not look us in the eye when they speak.
When the little ones want me to believe something that I have my doubts about, I always say, "Look me in the eye and tell me that." Their smile and shyness gives them away. So even children instinctively know that the eyes are the window to the soul.
And one thing I love about Lay is that when he smiles, his eyes smile with him. That doesn't happen with everyone. Yes, eyes really do reflect a person's beauty and personality.
