I am curious as to which frame you use and you say you only get about a year out of them. Do you break them from abuse or do the lenses get messed up. I have a appointment to go get my eyes checked and know I will at least need to get new lenses. I have had the ones I am wearing for probably five years or better but they were expensive getting them from my eye doctor. I see Zenni offers a similar Titanium wire framed model. I called and asked and they only have the plastic lenses and I have been using the glass lenses that haven't seemed to get scratched up with all the dirt and grit from farm work and the shop work I do. https://www.zennioptical.com/p/titanium-rectangle-eyeglass-frames-/1375?skuId=137516
