Ok, so I have a patient that bought her progressive lenses 2 years ago from Standard Optical and she's really liked the design. I called Standard to see if I could just make it easy and do use that same design on her new pair, but they told me one I haven't heard of yet. They said she's been in the MHD progressive lens. Does anyone know if that's just what they call a different lens, or if it's their house brand? Is it comparable to any other style? Thanks!
