Has anyone tried edc'ing spare contacts ? Seems an easy pocket sized solution.
( I'm also thinking of keeping my old - last prescription - glasses as spares in the car.)
I do carry spare contacts and solution whenever I'm traveling, but not as part of my EDC.
My big concern about spare contacts is temperature -- I would keep them in my BOB or my laptop bag, both of which can spend a great deal of time in the trunk of my car. This can lead to conditions that would destroy the contacts. Other than carrying spare glasses, I haven't figured out a good way to deal with this.
