They go by many names but this is an easy project if you have a little bit of time.  The idea is simple, make a strap to hold your glasses when not wearing them or making it tight on your head so as not to fall off.

Step 1: Items needed:

Items needed:

White silicone tubing - 3/16in inner diameter, 5/16in outer diameter, 1/16in wall.
Flexible adhesive
Paracord - 36 inches
Lighter - (or other source of fire to melt ends)
Rounded cord lock

Note:  Hobby shops also have loops that are used for holding glasses.  The loops are actually one loop with a crossbar to make a figure 8.  This can be used in a configuration instead of the tubing.

You could forgo the adhesive if you heated the paracord to the point where it balled up. Then insert it into your tubing and tie a constrictor knot of the inner strand materials. After that, you would pull back on the cord to snug it against the knot.

YouTube is an excellent source for constrictor knot videos.
