This Instructable describes a method of making a paracord lanyard to help keep your glasses on, or near, your head. Based on your adjustment of the cord, the glasses can either dangle on your chest, or be held snugly to the face. This method uses only paracord; some alternative approaches that incorporate additional materials are shown at the end.
Step 1: Materials
Paracord, about 1 yard (or 95cm)
Eye glasses or sunglasses (if you don't have these, well, why bother?)
Lighter (to singe cord ends)
Knife or Scissors (unless you have really sharp teeth)
Plastic Cord Lock
