Batman. He's conquered the comics. He's conquered the big screen. He's conquered Lycra and plastic composites armor. Now, he's here to take on eyeballs. Batman Contact Lenses make their wearers one with the Dark Knight's optics, as well as give them that unsettling, borderline maniacal look all unnaturally colored contacts tend to do. Bat Signal in the sky? Nay. Bat Signal in the eye.
Batman Contact Lenses are 14mm in diameter, with a base curve of 8.6. They are for aesthetic effects only, and are not available as prescriptive eyewear.
