| Oakley's X-Metals have an extremely rigid frame made of a titanium alloy. In order for you to actually be able to wear them (without stabbing your eyeballs out with the ear stems), they had to add some flex to the frame. |
| They did that by connecting nose bridge and orbitals with two press-fit pins that are cushioned by rubbers ("flex couplers"). These wear out over time letting those beautiful frames hang off your face like to drooping flower. Time to replace them. |
