Can the bridge of glasses be adjusted?
In this case, you can simply adjust the bridge or the angle between the lenses and the end pieces of the temples. If the angle has changed on only one of the temples, you adjust the angle between the lens and the end piece of the temple. If you want to adapt a plastic frame, you will need to use the hairdryer.
