The side blinders are designed to replicate the Juliet's/Penny's worn by Cyclops in the X-Men movies. Typically X-Metal in color and can be bought from a professional prop maker on eBay if your timing is right. He will also make a pair and add them to eBay if you contact him. GREAT collector's piece in my opinion.
P.S. These may or may not stay in place depending on the shape of your face. They're not designed to be permanently attached to your sunglasses.
