I bought these as replacements due to one of my original RayBan lenses getting cracked and chipped. They did fit the frames snugly and accurately, but they are also plastic and not in the same league as the original glass lenses. The polarization appears to be a little off as well compared to the original glass lenses as things like my phone screen seem to have a smeared multicolored haze on them. This goes away when I remove the sunglasses. With any other polarized lenses, if a screen is dark, rotating it 90 degrees will solve the problem. All in all, these lenses are just OK and will do the job until I either find some reasonably prices glass replacements or replace the sunglasses altogether.
