Black eye dye/drops ?

A friend of mine said there are special eye dye drops that you can use to dye the whites of your eyes black. They’re used in military night ops, and by a memeber of Limp Bizkit. I’ve searched for a while, and can’t find what this substance is or where it can be purchased. Has anyone heard about this stuff?

Contacts. Don’t know where you can get them. You can also get “blacklight” contacts- if you’ve seen the movie “Belly” (which I don’t really recommend) you’ll know what I’m talking about.

Allow me.

These are actually the same people, but each site has different pictures. A warning, though: I have never known of any actor who had to wear them liking them. Apparently the full eye contacts hurt like hell.
