They are the Square Wire 2.0. Similar to the T Wire but these are Aluminum based, while the T is titanium. - Dann

Thank you very much, Dann!

I can't determine what frames these are. I got them a long time ago and need to get new lenses as the coatings are finally coming off the lenses. I believe they are T-Wire 2.0 but I'm not sure. They're no markings on them except for "Polarized" on one of the lenses and a small CE by the ear rubber.
