Dan Radcliffe was allergic to the Harry Potter glasses!

Watch the conversation below between JK Rowling and Dan Radcliffe in which he explains how he went for a week without realizing that the white circles around his eyes were a result of him being allergic to the Harry Potter glasses. 

To give some context, it seems like it was the first pair of glasses he tried on and they were corrected later. They talk about how they're lucky they don't believe in signs, because if they did they probably would've thought that he wasn't meant for the role!
