So, I'm a former 20-year, state licensed, nationally cerified optician. Been out of that biz for a long time now though. Still, I always recommended polarized sunglass lenses to my customers, and now that I need reading glasses, but not really a distance correction, I have spend a lot of time assessing what glasses were available to me that did not cost an arm and a leg. I love that I finally found Onos! Polarized, mirror, bifocal lenses is exactly what I wanted, and these are fashionable and the optics are perfect! The sturdy frame fit me perfectly, which is not an easy order formy full cheeks and smaller bridge. I am just so very pleased and I know I will be ordering more in the years to come!
