Chris O`Crooh, IMO you are right to plan for at least one extra set of glasses. Contact lenses may require more regular maintenance than your emergency situation might allow, so make sure you have a pair of traditional eyeglasses with your current prescription. Pack a magnifying glass, too. There is nothing more frustration than having to repair your glasses without having them on your face! Any appliances you use regularly to assist you should have a high priority in your planning for a back-up. Good points.

There are several referrals on this site re: first aid kits and I recommend you study them. Your planning should also be sensitive to not having all your eggs in one basket. Consider making your bug out bag modular in ways to allow the loss of one section or pack will not mean the loss of all provisions for that critical contingency.
