Eye did not know this but Mattel launched in the 1980’s (1987) a series of interchangeable sunglasses called Hot Looks for adults and Cool Shades for kids. All the parts, front and temples were interchangeable. Right eye could be a bird and left eye could be a hamburger, temple could be a saxaphone. They were fun and whimsical, but no longer available today. You can find vintage on ebay.
