You sure? You ever actually try to crush lens? It's not regular glass

The frames are the easy part. The lenses are what's tricky. I wear polycarbonate lens myself. According to this data page from an industrial company, polycarbonate has a shear strength of 9200 psi (63.43 MPa) and a compressive strength of 11500 psi (79.29 MPa): https://www.polytechindustrial.com/products/plastic-stock-shapes/polycarbonate-pc-1000
Yet Matweb puts it's compressive strength at 18 to 86.2 MPa: https://www.matweb.com/search/DataSheet.aspx?MatGUID=501acbb63cbc4f748faa7490884cdbca

To be honest that's not particularly wrong or inconsistent. The first value of compressive strength falls within the range given for the second one, closer to the high-end. It's not very precise but it is consistent at least.
