Who really invented Glass, Google or Da Vinci?

Findings by University of Illinois researcher, DR. Burt Wilde have shown that Leonardo Da Vinci, the inventor, musician, artist of the 15th century, drawings portrayed what is believed to be the idea behind Google Glass. In the picture above, Leo drew himself wearing a device that looks very much like present day Google Glass. With these findings, do you think Google got the idea of Glass from Leonardo Da Vinci? let me know your thoughts in the comment.
