I don’t think they’re particularly out there. But, my god metal frames bloody hurt. I don’t know if it’s my nose or face shape or the fact I have a high prescription but the bits on the side push into my nose. I’ve got a permanent dent from an NHS pair I wore back in the day.
I’d say buy what suits your face and feels comfortable. Also, I only buy glasses when I’ve got my contacts in so I can see the frames properly.
