# I should always wash my hands before putting my contact lenses in - especially if the last thing I did (and had forgotten about) was slice shallots.
# Concealer stick hurts a lot if you get it into your eyes (same one as the contact lens problem - sadly)
# Dark sunglasses are usually suitable attire when the above 2 points have happened - even if they aren't prescription. No-one wants to see your 28 Days Later impression.
# Vicks vapourub also hurts when inadvertantly applied to the eyes (minus contact lenses thankfully)
The conclusions drawn - I need to wash my hands better and stop poking myself in the eye.
