These hang on to your glasses for you. They are amazing!

This is perfect for my sun during ball practice. He often took his glasses off and would lose them or they would fall off while playing ball. However, this slipped on his glasses with ease and keeps them securely around his neck. I no longer have to worry that he will lose them or that they will fall on the field and get stepped on. It's soft around his neck and he doesn't even notice it while he's playing.
