10. DIY Contact Lens Solution
Have you ever found yourself without any contact lens solution on hand? This is likely to become a very common issue after the SHTF, and this is one major reason that you should also have a pair of glasses. However, for as long as your contacts last, you can keep them clean with hydrogen peroxide. This substance is part of the commercial solutions for sensitive eyes, and it does the job very well on its own.
Hydrogen peroxide can also serve several other vital functions during the apocalypse, including sanitizing any surface, removing stains from your clothing and even helping you lighten your hair if you need to disguise your appearance. For all of these reasons and many more, hydrogen peroxide definitely deserves a spot in your bug out bag.
