Single Vision Freeform High Index 1.67 Lenses

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
You may want to order clear Single Vision Freeform High index 1.67 Lenses, which also gives you the option to add a tint to the lenses. This option is perfect for sunglasses, just note that high index lenses do not tint as dark as other lens types. You may also choose to order photochromic lenses, which are clear indoors and darken in the sun.
