This is caused by the deformation of the glasses frame. Most people are used to wearing glasses with one hand. Over time, the glasses frame will always be stressed, so over time, the glasses frame will be uneven. It is recommended to wear both hands to avoid external force squeezing or colliding with the glasses frame. Your frame is deformed, so you should go to the optical shop as soon as possible to find a professional to help you correct it. You shouldn't break it yourself to avoid damaging the lens or frame.
