Single Vision Freeform High index 1.67 Lenses are great for very strong prescriptions that will not work with Polycarbonate or Trivex. These lenses are thin enough and durable enough to work with drill-mount frames, or frames that connect the lens directly with the arms of your frames. High Index lenses are very reflective compared to other materials, which is why we include an anti-reflective coating to these lenses before we send them back to you, free of charge. We also throw in a free anti-scratch coating because who likes scratched glasses, and these lenses offer UVA and UVB protection.
Options for These Lenses
