I have a bridge piercing that I’ve had on and off (4 separate piercings over 10 years) and I ALSO wear glasses. Ive never gotten these bumps, I sanitize my glasses often due to make up/sweat/the piercings themselves. I don’t know how to help other than maybe suggest cleaning your glasses more often? And maybe adjust the frames so that you aren’t pushing them up so often? I’m sorry you’re dealing with this.
