DUE TO NEW YOUTUBE RULES PLEASE SUBSCRIBE! Nothing more annoying than a pair of prescription eye glasses breaking. It happens when it's inconvenient and is expensive as the old frames you have they don't make a new frame that will accept your old lenses. Good for them , Bad you YOU and ME. THis is a simple fix soldering the break with standard soldering tools. You can use any solder iron that melts solder. I have a Hakko 888D. I'm using it only because I have it for some electronics work I do
