Happy Eye Week! We are excited to bring you a whole week of episodes all about the spectacular ocular eye. For today’s episode, we know that glasses help people see, but exactly how do those little lenses work? We reached out to optometrist Dr. Kelsea Brown to help us find the answer.

Got a question whose answer you just can’t see? Send it to us at BrainsOn.org/contact and we’ll help lens a hand!
