Is eye cream worth the money?

I went to the makeup store to buy eyeliner and the saleswoman there asked what kind of eye cream I use to moisturize. When I told her I don’t use eye cream, she seemed shocked. She acted like it is a staple – and as if every woman should use eye cream to prevent wrinkles. However, when she showed me the eye creams, they were all upwards of $50. I’m look young for my age and don’t have any wrinkles yet, but wonder if eye cream is indeed as important as she said, or just a way for the cosmetics company to make a lot of money with a specialty item. So: Is eye cream worth it? Does it actually work to prevent wrinkles? And if so, are there any natural (paraben-free) brands that you would recommend? Thanks!
