A hot new drinking game is "vodka eyeballing" where drinkers pour vodka into their eye.

The side effects? Possible blindness.

Apparently, it causes them to get drunk very quickly, even though experts say only a small amount of alcohol gets into your system that way.

A new documentary interviews a young woman who played the game a lot. She went to an eye specialist and they told her the vodka made it's way through her cornea which can lead to blindness.
