What sunglasses does Ellen Page wear in Juno?

While it's not explicitly stated in the movie or behind-the-scenes information, Ellen Page's character Juno MacGuff in the film "Juno" appears to be wearing a pair of Ray-Ban Wayfarer sunglasses.

This is a popular guess based on the shape and style of the sunglasses seen in the movie. However, without official confirmation from the costume designer or Ellen Page herself, it's impossible to say for certain.
