Tool question (wire)

The kit comes with a flat spiral wire. It looks like a curled up plumb. I recall reading somewhere it’s for the loupe? Do I need to bend it up to hold the loupe hands free??

No need to bend iirc. The loupe goes into the smaller circle and the bigger open circle goes around your head

Huh. I thought of wearing it on my head to be funny. As it stands, I clipped it on my glasses and it worked great. But I may have to try the “wear on your head” method just for fun.
