Answer 7

Have a few beers and stay awake for 36 hours...that should do it.

Bloodshot eyes are usually the result of an irritation or overtiredness, dry eyes.......pretty hard to fake any of those.

It isn't a natural state to have bloodshot eyes, so any way to try and force it to happen is doing harm somewhere.
