If you have bought metal discount glasses, then you are lucky. Metal frames are the most bendable, and not so easy to break. Basically you can adjust four parts, which are the nose bridge, the nose pads, the temples arms and the ear hooks on the temples. For the nose bridge and the temple arms, you may use hand force to bend or twist these parts gently and carefully without any tools, and stop when you feel comfortable after putting on your face. For the nose pads, some of them can be adjusted by hand, while others can only be done by pliers. Remember to wrap the tips of the pliers with rubber and layers of cloth, so it won’t damage the surface of the metal.

The ear hooks are normally wrapped by plastic cover, so you need to heat this part before adjusting its angle. Some people recommend to use oven as the heat source by keeping some distance from the visible fire (not too faraway and not to close). But keep in mind not to overheat, and you need to test the pliability of the ear hook the way you go. This part needs to be done with caution.
