Not to blow my own trumpet, but I work in Optical Foresnsics. I’d have to see the frame in the metal to be sure, but from your photo, it looks like you have unbalanced ears – your left ear is both larger and slightly higher than the right. Probably hairy as well.
In layman’s terms, Dumbo, you’ve fed unsupportable stresses into the main body of the frame which has caused a crystalisation issue at a molecular level at the area of maximum auricular moment close to the bridge of your nose. Your specs have probably been on the verge of fracturing catastrophically for months now. To be brutal, you’re fortunate to still have both ears intact.
For your next frame, go custom steel or think about ear reduction surgery.
