        <p>How do glasses work? Why do some people need glasses and other people don’t? Why do we have different eye colors? We answer your questions about glasses and eyes in the second of two episodes with Dr. Sujata Singh, a pediatric ophthalmologist at the University of Vermont Medical Center. And we hear from Maggie, a kid with low vision, about what it’s like to need glasses. </p>
