My eyeglasses frame broken. Now it’s time to repair it. First sanding color coating, rust and clean any grease on the surface that you need to solder. Rub it until the surface looks shiny. Sanding another part until it look shiny too. Join the two part and solder them with lead-free solder wire. normal lead solder wire is toxic so avoid using it. The eyeglasses almost on your face all the time so healthy is the most important thing. Wait until everything cool down Removing excessive lead with sandpaper Bending the eyeglasses frame until it is in a good position. The joint part is strong enough in real life use. Over six months long and the eyeglasses frame still not broken again (24/2/2017) thumb up!!!
