For Those With Glasses and Contacts!
Your vision is very important to your ability to survive. If you rely heavily on glasses or contacts then you should consider adding related items into your EDC. Carry extra contact lenses, back up glasses, tools to repair your glasses with and other items of that nature. Consider a pair of sport style glasses that have shatterproof and scratch resistant lenses.
The more active you are in sparsely populated areas, the more you are at risk to needing more medical gear. Consider your daily risk and exposure to needing medical gear and carry the appropriate items in your EDC. Remember most medical needs can be scavenged from many common places.
