See the way out
This is a tip for all you partially sighted party-goers out there. Always pack a spare pair of contact lenses in whatever accessory you take out with you.
Anything from your pocket, bra or shoe will do, trust us you will be even more desperate without them. There's nothing worse than waking up 'bleary eyed' than actually waking up bleary eyed. Being able to see how to get out of your situation is pretty integral.
At the end of the day even if you can't see, people will be able to see you.
