How does vision work? Do carrots really help you see in the dark? Why does vision worsen with age, and is there anything you can do about it? Professor Glen Gole, Director of Ophthalmology at Queensland Children's Hospital, talks us through the anatomy of the eye, how sight develops during childhood, and different conditions that can affect vision. Queenslanders Jim and Tina share their stories about dealing with the possibility of losing their vision.
