Review on Adjustable Cotton Eyewear Retainer Glasses by Jarrett Love

Works great! Exactly what I was looking for. They hold the temples of my glasses in place and can be adjusted to keep my glasses from slipping without being too tight. There is a spring button on the bead to adjust the strap. Just release the button and the bead will snap into place. The elastic band ensures a comfortable fit and makes it easy to put on and take off the glasses without having to adjust them.
