Here are the steps to wearing a glasses chain:
1. Attach: Securely attach one end of the chain to the arm of your glasses with the open loops on the end.
2. Adjust: Find a comfortable length by adjusting the chain to your preferred position. Ensure it rests comfortably around your neck without being too tight or too loose.
3. Secure: Secure the other end of the glasses chain to the other glasses arm with the currently unused open loop.
