how to reshape plastic glasses
The side that is up in the air should be bent down. Most of the time, pressure needs to be applied at the nose piece. The methods for working with metal glasses are different from bending plastic ones. For metal frames, use soft pliers that have ends that are covered in plastic. Place a cloth over the glasses to help prevent them from becoming scratched or otherwise damaged. Use the pliers on top of the cloth. Place them where the frame is bent, and gently ease the glasses back into shape.
