I’ve never broken my frames but I also never sat on them. One set of glasses had the same frame for nearly ten years now and I’ve only replaced the lenses due to scratches. The only time I had an issue with lenses/frame breaking was when I had one of those “frameless frames” that are only connected to the glasses through a small point.

Thanks for taking your time to answer my questions!

If you sat on your glasses, you probably would need new lenses anyway or do you have a second pair at home? Or does the round shape mean that you could just order it online because the shape is so simple?
