X-Ray Specs

X-Ray Specs are an American novelty item, purported to allow the user to see through or into solid objects. In reality the glasses merely create an optical illusion; no X-rays are involved. The current version is sold under the name X-Ray Spex; a similar product is sold under the name X-Ray Gogs.
